10 New Programming Languages to Watch in 2021

Are you a programmer looking to expand your horizons and explore new, cutting-edge programming languages? Look no further than this list of 10 new programming languages to watch in 2021! These languages offer exciting new features and capabilities that could revolutionize the way we program in the future.

1. Rust

First on our list is Rust, a systems programming language designed for speed, safety, and concurrency. Rust has been gaining popularity in recent years thanks to its ability to eliminate common sources of bugs and crashes in software. It also offers built-in support for parallelism, making it ideal for high-performance computing applications.

2. Kotlin

Kotlin is a cross-platform programming language that targets the JVM, Android, and JavaScript. Developed by JetBrains, Kotlin has become increasingly popular in recent years as an alternative to Java, offering a more concise and expressive syntax, improved type safety, and support for functional programming paradigms.

3. Julia

Julia is a high-level, high-performance programming language designed specifically for numerical and scientific computing. It offers a combination of features that make it ideal for tasks such as data analysis, machine learning, and computational physics. Its syntax is similar to that of MATLAB, making it easy for users of that language to transition to Julia.

4. Go

Go is a systems programming language developed by Google, which has gained popularity in recent years thanks to its simplicity, concurrency, and speed. Go is ideal for tasks such as network programming, concurrency, and parallelism, and its modern syntax makes it easy to learn for programmers of other languages.

5. Dart

Dart is a client-optimized programming language developed by Google, which is designed to be fast, flexible, and scalable for building web and mobile applications. Dart compiles to JavaScript, allowing it to run on any browser, and has built-in support for reactive programming, making it an ideal choice for building modern web applications.

6. Crystal

Crystal is a statically-typed, compiled programming language inspired by Ruby, but with a much faster runtime. It offers syntax that is similar to Ruby and modern features such as type inference and macro programming support. It is designed for building high-performance, concurrent applications, making it ideal for web development and server-side programming.

7. Clojure

Clojure is a dynamic, functional programming language that targets the JVM and CLR, offering seamless interoperability with Java and .NET. It offers a rich set of immutable data structures, support for concurrent programming, and a concise, Lisp-like syntax, making it an ideal choice for building highly scalable, fault-tolerant applications.

8. ReasonML

ReasonML is a new syntax for the OCaml programming language that brings modern JavaScript syntax and semantics to this well-established functional programming language. ReasonML provides a simple way to write type-safe JavaScript code, making it ideal for building web applications using React.

9. Elixir

Elixir is a dynamic, functional programming language designed to run on the Erlang virtual machine, offering excellent support for concurrency and fault tolerance. Elixir's syntax is similar to Ruby and its built-in support for metaprogramming and macros makes it ideal for building distributed, fault-tolerant web applications.

10. Swift

Swift is a multi-paradigm programming language developed by Apple, which is used for building iOS and macOS applications. Swift offers a modern, expressive syntax, improved memory safety, and built-in support for concurrency, making it an ideal choice for building high-performance, robust mobile applications.


These 10 new programming languages all offer exciting capabilities and features that make them ideal choices for a wide range of applications. Whether you are interested in building high-performance applications, exploring new paradigms in software development, or simply looking to expand your programming horizons, these languages are definitely worth keeping an eye on in 2021 and beyond!
