Available industry figures give us no definitive answer to the question “Kotlin vs Golang”. Take Statista, for instance. Indeed, they have some info concerning 2023. In their ranking, Go is the 13th pick for software engineers worldwide, with a 13% share. Kotlin lags, yet not radically. It is 15th, accounting for 9%. Speaking of growth rates of these programming languages, they are also comparable: Back in 2022, according to GitHub, Kotlin vs Golang comprised 23% vs 29% accordingly; The 2023 landscape is also comparable, not too different from 2022. Finally, if one looks at the well-known Popularity of Programming Language Index, Kotlin and Go will be “neighbors,” 13th and 12th, respectively, with approximately 2% and 2.3% market shares, respectively. We at CHILLICODE closely track trends and developments associated with modern programming languages. Behind these seemingly equal “rivals'', Kotlin and Go, we recognize different roles and potentials. Today, we will elaborate on them. {{ "title": "Write ChilliCode", "description": "To help you acknowledge your business needs and decide whether IT services will work for you, I’ve sorted out a list of cases.", "buttonText": "Contact us" }} Kotlin Defined Kotlin is a representative of good old statically typed programming languages. Being a general-purpose path, Kotlin takes pride in versatility, conciseness, safety, interoperability, and a range of genuinely present-day features. Its initial task was to serve the Java Virtual Machine and Android app development needs. However, its pros, encompassing concise syntax coupled with null safety and extension functions, transformed it into a matching candidate for various digital missions. Among other things, it can be used for: Android app development goes without saying, by default; Crafting backend services and APIs. Many teams adopt it for server-side applications due to its clarity, safety mechanisms, and interoperability with the Java frameworks in existence (like, say, Spring Boot); Based on Kotlin Multiplatform, cross-platform mobile engineering gives a chance to write shared business logic. This enables one to utilize the latter across multiple platforms like Android, iOS, and even web apps, reducing duplication issues and speeding up the flow (yet, full-fledged cross-platform initiatives might still require platform-specific code for specific features and UI elements); Kotlin's support for functional programming paradigms and its concise syntax make it well-suited for crafting microservices. Combined with frameworks like Micronaut or Vert.x, Kotlin can streamline the successful development of scalable and reactive microservices; Kotlin code can be used to build desktop applications, relying on frameworks like TornadoFX. Its expressive syntax and conformity with Java libraries, as we have already mentioned, make it suitable for creating GUI-based solutions; Kotlin is being used, to a limited extent, in Data Science and ML-specific IT projects due to its syntax, strong typing, and complete harmony with the aforementioned Java libraries and frameworks that are commonly used in these domains. Go Defined Go, frequently mentioned as Golang, is another statically typed modern programming language renowned for its simplicity, productivity, and concurrency support. Initially envisioned by the Google team and first released in 2009, Go was designed to address the shortcomings of prevalent languages while providing an up-to-date and pragmatic approach to software. With its straightforward syntax, built-in concurrency primitives, and outstanding compilation speed, Go has gained popularity. Among other things, Go can be used for: Golang code is apt for web development and APIs. Frameworks like Gin and Echo provide swift, minimalistic solutions for scalable and efficient web servers. Go's library includes potent packages for tackling HTTP requests, routing, and middleware, simplifying the development flows; Go's goroutines and channels make it a match for microservices-based architectures. Combined with frameworks like Go kit or Micro, Go can facilitate the development of distributed systems by giving one tools and patterns for service discovery, load balancing, and fault tolerance; Go's static linking and cross-compilation capabilities make it a deal for working on command-line tools and utilities that would be concurrently fast, efficient, and portable; Go can be adopted for cloud-native development, where scalability, resilience, and performance are critical. Projects like Kubernetes, Docker, and Terraform are written in Go, highlighting their suitability in this context. Go's in-built support for concurrency and networking naturally makes it a proper choice for network applications, such as TCP/IP servers, HTTP servers, and WebSocket servers; Go's performance and ease will be helpful factors for data processing and analytics missions, such as ETL (Extract, Transform, Load) pipelines, data aggregation, and data visualization. Libraries like Gota and Gorgonia provide tools for working with datasets and implementing ML algorithms (to some extent, again, Python or R are still dominant choices); Go's limited memory footprint, effective concurrency model, and cross-compilation potential make it adapted to engineering applications for IoT devices. Projects like Gobot provide a framework for building IoT applications in Go, enabling IT professionals to interact with sensors, actuators, and other IoT peripherals. Comparing Kotlin with Go as compiled languages Kotlin Go Kotlin differs here, as it was from the very outset oriented towards the Java Virtual Machine. So, when one creates code in Kotlin, it needs to be compiled into bytecode before it can be executed. Here, source code is typically compiled to Java bytecode, on that very Java Virtual Machine. Conversely, Kotlin also supports compilation to JavaScript for web development and native binaries for platforms like iOS and embedded systems. When one generates code in Go, they compile it into machine code. The latter can subsequently be executed directly by a computer's processor. The Go compiler translates Go source code into machine code that can run on various platforms and architectures. This compilation process results in standalone executable binaries that do not require an interpreter or virtual machine to run, contributing to Go's efficiency and portability Kotlin vs Golang: Some History to Reflect Upon Briefly, Kotlin’s history can be presented as follows: History of Kotlin can be traced back to 2010. It emerged for a reason. JetBrains, a well-known software development hub, well-known for integrated development environments, started to work on a fresh promising option for engineers. The rationale behind this decision was to tackle a range of limitations and issues engineers were facing with existing programming alternatives (Java, in particular, which was widely used by JetBrains' Java developers digital products); In 2011, the JetBrains team announced their open-source initiative; In 2016 Kotlin 1.0 was released; 2017 was a double milestone for Kotlin. First, it started to enjoy Google’s official support on Android. Its popularity in the Android app development community skyrocketed. Second, Kotlin Native entered the game. As an extension, the latter allows engineers to compile Kotlin code directly to native binaries, with no need to rely on the Java Virtual Machine. This advantage enables the development of native applications for various platforms, including iOS, macOS, Windows, Linux, and even embedded systems; In 2019, Multiplatform Projects - Kotlin 1.3 was released, introducing significant features like coroutines and multiplatform projects. Those make it possible for engineers to share code between different platforms, e.g. JVM, JavaScript, and native; The latest version available now is 1.9.24. As for Go, its trajectory is: History of Go can be traced back to 2007 when Google engineers initiated its development. The motivation behind creating Go stemmed from the need for a modern and efficient language that could address the challenges faced in large-scale software engineering projects. Go was designed to offer the performance of compiled languages like C++ while maintaining the simplicity and readability of interpreted languages like Python; In 2009, the first public release of Go was made available; 2012 was a significant year for Go, as version 1.0 was released, signaling its readiness for production use; In 2015, Go's official support for cross-compilation was introduced, empowering developers to build binaries for versatile platforms and architectures from a single codebase. This feature enhanced Go's appeal for cross-platform applications and command-line tools; In 2018, Go 1.11 was released, introducing modules as a first-class citizen in the Go ecosystem. Modules provide a scalable and reliable solution for managing dependencies in Go projects, addressing a longstanding pain point for Go developers; 2019 saw the release of Go 1.13, which introduced improvements to the garbage collector, performance optimizations, and enhancements to the tooling ecosystem; The latest version of Go accessible now is 1.17. Kotlin vs Golang: A Comparison The moment has come to assess Kotlin and Go in light of, first, their similarities and differences, as well as strengths and weaknesses. Kotlin and Go: Similarities and Differences Kotlin and Go, while both up-to-date statically-typed programming languages, exhibit distinct differences in their language features and design philosophies. On the one hand, Kotlin emphasizes interoperability with Java (which is good news for countless Java developers worldwide) and focuses on conciseness, safety, and expressiveness. Its syntax, influenced by Scala and Groovy, offers features such as null safety, extension functions, and type inference, enhancing professional productivity and code readability. On the other hand, Go prioritizes simplicity, efficiency, and intuitiveness. Its minimalist syntax, inspired by C and Pascal, aims to reduce complexity and verbosity while providing powerful concurrency primitives, e.g. goroutines and channels. Go's design philosophy revolves around providing a straightforward and pragmatic approach to crafting scalable and efficient software, making it practical for up-to-date distributed systems and network applications. While both compiled languages share similarities such as static typing and support for concurrency, they diverge in their approach to error handling, package management, and inheritance. Kotlin offers latter-day language features like coroutines for asynchronous programming and higher-order functions for functional programming paradigms. At the same time, Go promotes idiomatic patterns for concurrent and parallel programming through goroutines and channels. Let’s dive in some more specific points of divergence between these compiled languages in this table: Kotlin Go Kotlin and Go, their syntax and expressiveness Kotlin features a streamlined syntax that minimizes redundant code and improves readability. By upholding functional programming concepts, it empowers developers to articulate intricate concepts with clarity and brevity. Go prioritizes simplicity and readability in its syntax, favoring explicitness over brevity. While its syntax may seem verbose compared to Kotlin, it excels in promoting code maintainability and team collaboration Kotlin and Go, their memory usage management and performance Being a JVM-based language, Kotlin inherits Java's memory usage management model, which may lead to higher memory usage compared to languages like Go. However, Kotlin's performance is still commendable, especially in scenarios where the Java ecosystem is leveraged effectively Go's efficient memory usage management and compilation to machine code result in really high-performance, particularly in CPU-bound tasks and memory-intensive applications. Its lightweight goroutines provide for concurrent execution without the overhead of heavyweight threads, further enhancing performance and scalability Kotlin and Go, their concurrency and parallelism Kotlin provides support for concurrency through its coroutines feature, which enables one to write asynchronous and non-blocking code with ease. While coroutines offer flexibility and expressiveness, they rely on underlying threads managed by the JVM, which may limit scalability in highly concurrent scenarios Go's built-in concurrency primitives, namely goroutines and channels, facilitate the creation of highly concurrent and scalable stuff. Goroutines are lightweight, user-space threads that fuel concurrent execution of tasks, while channels provide a safe means of communication between goroutines. This combination of concurrency features makes Go well-matched for building scalable and responsive systems Kotlin and Go, their error handling and robustness Kotlin promotes robust error handling through its type system, which includes features such as nullable types, smart casts, and sealed classes. By enforcing null safety at compile time, Kotlin helps developers pin down potential null pointer exceptions early in the development process, thereby enhancing code reliability and maintainability Go follows a pragmatic approach to error handling, where functions return error values explicitly, allowing one to handle errors gracefully and propagate them as needed. While this approach may seem verbose compared to languages with exceptions, it encourages explicit error handling, leading to more robust and predictable code Kotlin and Go, their tooling and engineering environment Kotlin enjoys strong support from integrated development environments like IntelliJ IDEA and Android Studio, which offer advanced features such as code completion, refactoring, and debugging support. Additionally, Kotlin's interoperability with Java makes it possible to leverage existing Java tools and libraries seamlessly Go comes with a lightweight and efficient toolchain, encompassing the go command-line tool, which simplifies package management, compilation, and testing. IDEs like Visual Studio Code and JetBrains GoLand provide excellent support for Go development, with features tailored to Go's syntax and workflow Kotlin and Go, their ecosystem and community support Kotlin capitalizes on the extensive Java ecosystem, embracing libraries, frameworks, and tools, which enhances its versatility and adoption. Moreover, Kotlin's official support for Android app development has garnered significant community traction, leading to the emergence of robust libraries and frameworks tailored for mobile development Go's standard library is exhaustive and well-designed, incorporating a broad range of functionality for building web servers, networking applications, and concurrent systems out of the box. Additionally, Go's growing community actively contributes to the ecosystem by developing open-source libraries and tools, further enriching its ecosystem Some Syntax Samples of Two Modern Programming Languages These examples seek to highlight the difference we have mentioned. Kotlin prioritizes conciseness and readability, while Go puts strong emphasis on simplicity and explicitness. Kotlin Go Task: Variable declaration and initialization val message: String = "Hello, Man!" message := "Hello, Man!" Task: Function declaration fun greet(name: String): String { return "Hello, $name!" } func greet(name string) string { return "Hello, " + name + "!" } Task: Loop (For) for (i in 1..5) { println(i) } for i := 1; i <= 5; i++ { fmt.Println(i) } Task: Control structures (If-Else) val x = 10 val y = 5 if (x > y) { println("x is greater than y") } else { println("x is less than or equal to y") } x := 10 y := 5 if x > y { fmt.Println("x is greater than y") } else { fmt.Println("x is less than or equal to y") } Task: Slices (Array-like Data Structure) val numbers = listOf(1, 2, 3, 4, 5) numbers := []int{1, 2, 3, 4, 5} Task: Concurrency (accounted for by Goroutines in Go and Coroutines when Kotlin is involved) import kotlinx.coroutines.* fun main() { GlobalScope.launch { delay(1000L) println("World!") } println("Hello,") Thread.sleep(2000L) } package main import ( "fmt" "time" ) func main() { go func() { time.Sleep(1 * time.Second) fmt.Println("World!") }() fmt.Println("Hello,") time.Sleep(2 * time.Second) } Unique Features In the capacity of modern programming languages, each of the alternatives we examine here goes with a set of unique differentiators one cannot find the opposite option. Go’s Differentiators One-of-a-kind leverage # 1. Goroutines and channels. Go's built-in concurrency primitives, goroutines, and channels, enable easy and efficient concurrent and parallel programming. Goroutines are lightweight threads managed by the Go runtime, and channels facilitate communication and synchronization between goroutines. This concurrency model is not directly available in Kotlin, although Kotlin does provide support for asynchronous programming through coroutines. One-of-a-kind leverage # 2. Deferred error handling. Go's error handling approach, based on explicit error return values, allows developers to handle errors directly where they occur, without the need for exceptions or try-catch blocks. This approach simplifies error handling and promotes explicitness in code, differing from Kotlin's exception-based error handling mechanism. One-of-a-kind leverage # 3. Static linking and cross-compilation. Go's static linking and cross-compilation capabilities enable developers to produce standalone binaries that are portable across different platforms and architectures. This feature simplifies deployment and distribution of Go applications, particularly in environments with diverse operating systems and hardware configurations. One-of-a-kind leverage # 4. Built-in tooling. Go comes with a rich set of built-in tools, including the go command-line tool for building, testing, and managing Go projects, as well as tools like gofmt for code formatting and govet for static analysis. These tools enhance developer productivity and streamline the development workflow. Kotlin’s Differentiators One-of-a-kind leverage # 1. Null safety. Kotlin provides built-in null safety features that help developers escape null pointer exceptions and NullPointerException errors, which are commonly encountered in languages like Java. Kotlin's type system distinguishes nullable and non-nullable types, allowing developers to write safer and more robust code. One-of-a-kind leverage # 2. Extension functions. Kotlin allows developers to add new functionality to existing classes without altering their source code through extension functions. This feature promotes code reuse and modularity, allowing developers to enhance the functionality of libraries and frameworks without subclassing or modifying their implementation. One-of-a-kind leverage # 3. Coroutines. Kotlin's coroutines enable easy and efficient asynchronous programming by abstracting away the complexity of managing threads and concurrency. Coroutines permit us to write asynchronous code, making it more straightforward to maintain asynchronous codebases. One-of-a-kind leverage # 4. Type inference. Kotlin's type inference mechanism automatically deduces the types of variables and expressions based on their usage context, diminishing explicit type annotation requirements and improving code readability. This feature reduces boilerplate code and enhances developer productivity without sacrificing type safety. Relative Weaknesses Comparing Kotlin with Go, one cannot omit not only their more or less unique, from this standpoint, strengths, but also have to pay attention to their weak spots. Soft spots with Kotlin as a modern programming language: Weakness of compilation overhead. Kotlin's compilation process can be slower compared to Go, especially in larger projects or projects with complex codebases. This may result in longer build times and slower iteration cycles during development, particularly in scenarios where rapid feedback is crucial; Weakness of learning curve for concurrency. While Kotlin supports concurrency through features like coroutines, the learning curve for understanding and effectively using these features may be steeper compared to Go's goroutines and channels. Developers transitioning from languages with different concurrency models may find it challenging to grasp Kotlin's approach to concurrency and asynchronous programming. Soft spots with Go as a programming language Weakness with the lack of generics. One of Go's significant limitations, especially in comparison with Kotlin, is its lack of support for generics. This can lead to code duplication and reduced type safety in certain scenarios, as developers may need to resort to using interface{} or casting to work with collections of different types. Kotlin's support for generics makes it more flexible and expressive in handling complex data structures. Weakness with error handling verbosity. Go's error handling approach, based on explicit error return values, can result in verbose and repetitive code, especially in functions that need to propagate errors through multiple layers of abstraction. Kotlin's exception-based error handling mechanism provides a more concise and expressive way to handle errors, making the code easier to read and maintain. Kotlin and Go: Web Development Capabilities As web development challenges have always been of particular interest to us at CHILLICODE, we would like to shed some extra light on this division as well. Kotlin Kotlin, with its strong interoperability with Java, can leverage well-established Java web frameworks, such as Spring Boot and Vert.x, for web development. Spring Boot provides a comprehensive set of tools and libraries for building enterprise-grade web applications, offering features like dependency injection, MVC architecture, and robust security mechanisms. Vert.x, on the other hand, is a reactive toolkit that allows for building high-performance, event-driven applications with asynchronous I/O. Additionally, Kotlin has its own web frameworks like Ktor, which is lightweight and designed for asynchronous programming, making it suitable for building modern, scalable web applications. Go Go's simplicity, performance, and built-in concurrency make it well-suited for web development, particularly for building high-performance, scalable web servers and APIs. Popular Go web frameworks like Gin and Echo provide minimalistic yet powerful solutions for developing web applications. Gin offers a fast HTTP router and middleware framework, while Echo focuses on simplicity and ease of use, allowing developers to quickly build robust web applications with minimal boilerplate code. Go's static typing and efficient memory management contribute to fast execution speeds and low resource consumption, making it an excellent choice for web applications that require speed, reliability, and efficiency.
