Top Programming Languages 2020

With something like 600+ programming languages floating around in cyberspace and dramatic shifts in demand based on the top coding trends, it’s hard to keep track of which programming languages are in or suddenly out. In 2020, Python, Java, JavaScript, C, C++, and C# continue to reign supreme, proving they’ve got real staying power that stands to continue into 2021 and beyond.

In this guide, we’ll look at the top programming languages of 2020–from the mainstays we just mentioned to some emerging coding trends.

Top Programming Languages are a Moving Target

Software programmers learn certain programming languages while in school or to do their job. However, the nature of software development is that there’s always something new to learn. As such, learning a programming language is not a one-and-done thing.

With hundreds of languages already in existence and a continuous stream of new entrants, programmers must continue to educate themselves about the newest and best programming languages.

While this isn’t an exhaustive list, here’s a look at the most popular programming languages of 2020.

Icons of Top Programming Languages


Python is a general purpose programming language currently ranked third on the TIOBE Index and 4th in-demand by Stackflow. Python plays a central role in developing AI and data analytics programs, as well as developing deep learning and machine learning capabilities. This means that we expect demand to continue to rise as these technologies become more widespread.


Java has been around for a while and doesn’t appear to be going anywhere. It is one of those programming languages worth learning because there is plenty of demand for programmers who know Java. If you want a job in the corporate world, this is simply a must-know language.


If you ask just about any programmer what one of the most popular and in-demand programming languages is, they will probably tell you JavaScript. It is an essential tool for front-end web development. Regardless of what issues you may have with JavaScript, it is hard to deny that it is a useful and a language that is used a lot, so don’t expect to see it go anywhere anytime soon.


Everywhere you look as a programmer, you will see C/C++ language being used.
While it is one of the harder programming languages to learn, if you are a programmer that prefers working at the system-level, this is a language to learn as soon as possible!


Designed by Microsoft, C# has many similarities to C++ and is used primarily to program native Windows applications; but it can be used for other platforms as well. It is also quite popular for building phone apps and Virtual Reality.


PHP is a widely-used open-source programming language for scripting. It’s well-suited for web development projects and can easily be embedded directly into HTML.

According to TIOBE rankings, PHP landed in the number 8 position in January 2020 and has maintained its ranking ever since. PHP isn’t exactly a “trending language,” and there’s a lot of debate around whether it’s dying out or in it for the long-haul.

That said, the development community has been continuously improving open-source standards for the past three decades. Its widespread use makes PHP a top programming language among employers.


R is a programming language used for data analysis and machine learning applications. The open-source language is currently the 9th most popular programming language according to the TIOBE index–up 10 points from last year. R offers a solid framework and built-in libraries for fast-tracking ML algorithm development and is widely used for statistical computing.

R also allows you to connect to a wide range of databases and pull data, and along with Python and SQL, making it one of the most popular programming languages among data scientists.


Go, or Go Lang, is an open-source programming language developed in 2007 by Google for web apps and APIs. Over the past few years, the programming language has started gaining serious traction.

According to a recent Hired report, Go is the most sought-after programming language among companies hiring software engineers, known for its flexibility, clean syntax, and problem-solving capabilities. Go can be used for a wide range of applications from big data and machine learning to video editing and network programming.


TypeScript is an extension of JavaScript, developed and released by Microsoft in 2014. TypeScript allows users to be more explicit about the data used in your code by adding annotations to your variables–making it easier for developers to catch mistakes in their code as the project scales.

According to the Hired data we just mentioned, TypeScript came in fourth among programming languages in-demand for software engineers.


Kotlin is a programming language used primarily for developing Android applications. Part of the Java Virtual Machine (JVM), Kotlin can be used anywhere you use Java–including client-side, server-side, and backend web development. Kotlin is gaining traction among developers for several key reasons; it enables faster development by allowing developers to write fewer lines of code, supports large-scale projects, and comes with several powerful development features.

It’s also fully compatible with Java and offers JavaScript report and interoperability, making it perfectly suited for multi-platform development.


Swift is an iOS-specific programming language used to develop apps for Mac, iPhone, iPad, and the Apple Watch. Swift is backed by Apple and comes with a clean, easy-to-read syntax and offers interactive development experience designed to make software development accessible to a broader range of users. Despite its low barrier to entry, Swift developers are both in demand and well-paid, as the programming language is essential for anyone creating apps for Apple devices.


Scala is a top programming language built on top of Java to extend its capabilities, while also allowing for compatibility and interoperability with its predecessor.

The general-purpose language supports both functional and object-oriented programming and aims to improve the performance and code quality you’d typically get using Java; it allows developers to perform the same tasks using fewer lines of code.

Due to its use in real-time data analysis, data streaming, machine learning, and other systems that involve big data and distributed systems,Scala’s demand continues to rise.


Rust is a general-purpose, C-like language, but has many differences and advantages – particularly the fact that it is much safer than C languages. It is a low-level code, ideal for systems. Because it is a managed code from beginning to end, it is far less vulnerable to security threats than other code.
