Summary: 'What are the top programming languages of 2021' -are you also looking to answer this.? Here you go. This blog represents a list of top programming languages that will help developers set a strong foundation in software and app development.

Programming and developer communities are emerging at a great rate of interest. Programming languages are gaining attention for different use cases and services they deliver to different developers. Having said, it is not easy for a beginner to determine the best-fit language to begin. It's even tough for an expert to understand which language they want to master. But you need not worry. This article highlights the top 10 programming languages that coders should learn in 2021.

List of 10 Best Programming Languages

1.Go
2.Python 3
3.Rust
4.Elixir
5.TypeScript
6.Elm
7.Dart
8.Pony
9.Kotlin
10.Reason

1.Go

Go (or Golang) is relatively a new system-level programming language developed by Google. It has simple scoping rules and focused vocabulary. It holds the best features of object-oriented styles and functional programming. Go is the fastest-growing language on Github, intended to replace popular languages like Java and C++.

Also, Go solves issues like slow compilation and execution in large, distributed software systems. Thus, Go is a crucial component for cloud infrastructure.

Top Companies Using GO

Uber, Dropbox, Twitch, Netflix, American Express, Salesforce

2.Python 3

Python is one of the most popular programming languages having clear and brief syntax features. Developers can use this high-level and interpreted language for web and desktop applications, GUI-based desktop applications, machine learning, data science, and network servers.

Python has excellent community support and offers several open-source libraries, frameworks, and modules, making application development a cakewalk. Even if you have hands-on experience in Python 2, using Python 3 is relatively easy. Why? As it has more intuitive code with comprehensive safety.

Instagram, Spotify, Amazon, and Facebook

3.Rust

Rust has marked its presence directly to the developer's community heart. It is one of the most loved languages, according to the Stack Overflow Developer Surveys. This static multi-paradigm programming language focuses primarily on performance and security. It ensures memory safety barring garbage collection, meaning the execution speed does not slow down. Its syntax is just like C++ and is very light, simple, and fast. The key USP to Rust is its error management strategy.

Top Companies Using Rust

Dropbox, Mozilla, Microsoft, Oracle, Atlassian, Yelp, Chef

4.Elixir

Elixir is one of the best functional programming languages highly influenced by Erlang. It's perfect for web and software development. Thanks to Erlang's VM, Elixir can quickly develop fault-tolerant, low-latency, and efficient software applications. Elixir developers work along with the Phoenix framework in most cases. Phoenix derives some of the top features of Ruby on Rails and takes them to a whole new level of performance. Elixir works well for high-traffic systems, have many connections, or are I/O bound.

Top Companies Using Elixir

Adobe, Netflix, Pinterest, Financial Times, Motorola Solutions, WhatsApp

5.TypeScript

TypeScript is a multi-paradigm programming language, developed and maintained by Microsoft. It is JavaScript's syntactical superset and adds optional static typing to the language. Developers use TypeScript to create large applications, and trans compiles to JavaScript. You can even use it to develop JavaScript applications for both client-side and server-side execution. It also provides coders with better interface modules, more effortless coding, navigation, error management, etc.

Top Companies Using TypeScript

Microsoft, Slack, Accenture, medium.com, Vox Media, Avanade, Asana, Lyft

6.Elm

Elm is a purely functional, domain-specific, strongly typed, reactive, and event-driven web client language. You can use it with or without JavaScript to create user interfaces on the web. Elm's primary benefits include consistency, maintenance, and programmer delight. One of the significant benefits that make Elm stand apart from the crowd is speed. Popular languages such as Angular, Ember, and React also lags.

Top Companies Using Elm

IBM, CBANC Network, Drip, Zalora, Acko Insurance

7.Dart

Dart is an open-source, general-purpose, object-oriented programming language with C-style syntax. It is an excellent alternative to JavaScript for programming in modern web browsers. Google's own software development kit (SDK), i.e., Flutter and the advertising tool Google Ads, depends on Dart. Isn't this great? You can use it to program laptops, smartphones, and tablets. You can even create frontend user interfaces for the web and mobile apps.

Top Companies Using Dart

Google, Blossom, Workiva, Adobe, Health Dynamics, Soundtrap

8.Pony

Pony is another evolving programming language. It is an open-source, object-oriented, actor-model, capabilities-secure, high-performing language. The reason for its popularity is the capability to solve the most complex problems faced by computing systems. Pony's significant highlights include type-safe, exception-safe, memory-safe, data race free typing, reference capabilities, and deadlock-free.

9.Kotlin

Kotlin is a most loved popular programming language. JetBrains, which is interoperable with Java and supports functional programming languages, developed it. At present, Kotlin is ideal for Android development, web development, desktop application development, and server-side development. Kotlin boasts features like- null safety, operator overloading, data classes, etc. As a license-free language, it has good community support.

Top Companies Using Kotlin

Coursera, Pinterest, Basecamp, Expedia, Trello, Amazon, Capital One

10.ReasonML

ReasonML is a syntax extension for the OCaml language. You can write simple, fast, and quality type safe code while leveraging both the JavaScript & OCaml ecosystems. It provides users with a strong-typed, clean, and efficient syntax for JavaScript, making it great for web development. Reason supports JavaScript as a compile target. It interacts with existing JavaScript code via an FFI (foreign function interface).

Another significant advantage covers: ReasonML has the potential to become a full-stack programming language, allowing you to write both frontend and backend code.

Top Companies Using ReasonML

Instagram, Stack, Rung, Broadsheet, Th3rd Wave

Wrapping Up

All coders have a desire to learn new languages. However, knowing which languages are gaining popularity is beneficial. All programming languages mentioned here are at par excellence. You can choose to learn any language based on your requirements and infrastructure.

According to me, there is no "best" or "worst" programming language, it all depends on the context and your use case. As you said, we should choose what is best for solving a problem rather than going behind the hype. Cheers!

1. Go

Also, Go solves issues like slow compilation and execution in large

That's relative. Yes, C++ is notoriously slow to compile, but C is still very fast and from what I've heard produces much smaller binaries than go.

2. Python

From a job perspective this might hold some merit, but generally, python isn't really a good language in my opinion. It often gets praise for how expressive it is, but from all I've seen, it's just an average scripting language.

3. Rust

Haven't used it myself, so I can't really comment. I'd certainly pick it over C++ if I was to learn either, even despite already knowing a good bit of C, but so far it only seems worth learning if you actually need it, and it does fill a rather small niche.

4. Elixir

I can absolutely agree. Specially for those who haven't really done any functional programming, learning Elixir is at the very least an awesome learning opportunity and looks good on a resume, and at best can be a very powerful tool for several areas where concurrency is important.

5. TypeScript

Just don't. Adding a broken type system on top of a mediocre scripting language doesn't make it any better. Unless you already use JavaScript and constantly find yourself wishing "if only it had types", this one is certainly a skip.

6. Elm

Haven't tried, haven't read much. Sounds very interesting on paper and, just as with elixir, at the very least it would be a good learning experience for those who haven't done any functional programming yet.

7. Dart

Correct me if I'm wrong, but dart isn't going anywhere. It completely failed to take off outside of some niche areas and, unless it manages to pull off a good late start, it's unlikely to make it very far before google inevitably trashes the whole project.

8. Pony

I must admit, I have never even heard of that language. This is probably because I'm not very interested in new object-oriented languages, but I will definitely have a look at it now.

9. Kotlin

This one looks like a good alternative to Java. I wouldn't pick it over any other language if I wasn't forced to use the JVM, but it would certainly be worth learning, considering JVM is still very relevant and Javas image problem is only growing due to newer languages evolving to be less and less verbose.

10. ReasonML

This is probably what you want to learn instead of typescript. Not only is it more different from JavaScript (which you either know already or should definitely learn first), meaning there's more new concepts to be explored, but it seems to be much more focussed on having a sane type system.


Well, those are my thoughts on all 10 of those languages. Very nice article and it's nice to see some languages other than the typical mainstream big names that everybody knows about already :D

Perhaps you could elaborate as to how typescript's type system is broken?

I will dive deeper, when I'm done with other 15 language..

Just a note: Reason also transpiles to JS, same as TS though it's a bit more than a JS superset as it almost completely deals with the shortcomings of JS as opposed to TS (which mostly brushes over)

Pony is as rare as Idris...

It is pretty cool that you put Pony on this list 🙂.
