The Most Popular Programming Languages

The popularity of a programming language is a good indicator of its usefulness and widespread adoption in the industry. According to the latest TIOBE Index, the most popular programming languages in 2022 were:

  • Java
  • Python
  • C++
  • C#
  • Visual Basic .NET
  • JavaScript
  • PHP
  • SQL
  • Swift
  • R

Java continues to be the most popular programming language, followed by Python and C++. These languages are widely used in the industry, have a large community, and offer various career opportunities.

Learning one or more of these programming languages can provide a solid foundation for your programming career.

The Most In-Demand Programming Languages

In addition to popularity, it is important to consider the most in-demand programming languages. These are the ones employers are looking for and are expected to have high growth in the coming years. According to the latest Stack Overflow Developer Survey, the most in-demand programming languages in 2022 were:


  • JavaScript
  • Python
  • Java
  • TypeScript
  • Rust
  • Kotlin
  • C#
  • Go
  • SQL
  • Swift

JavaScript tops the list as the most in-demand programming language, followed by Python and Java. This is not surprising given the widespread use of JavaScript in web development and Python’s versatility in various domains.

It is worth noting that new programming languages like Rust and Kotlin are also gaining traction and are expected to have high growth in the future.

Emerging Programming Languages

As the world of tech never stops spinning, it is important to also keep an eye on emerging programming languages, especially if you are already familiar with the most popular ones.

These are the programming languages that are gaining popularity and are expected to have high growth in the future. Developers that pay more attention to them right now will be in advantage once they receive higher demand.

Some of the emerging programming languages to watch in 2023 are:

  • Julia
  • Dart
  • Raku
  • Zig
  • V
  • HCL
  • Lua
  • Crystal
  • Rust
  • Kotlin

To provide a quick overview of these, Julia is a high-performance language for scientific computing, while Dart is a language for building web and mobile apps. Raku is a multi-paradigm language that combines features of Perl, Ruby, and other languages.

Zig is a low-level language that emphasizes safety, performance, and predictability. V is a simple and fast language for building system software. HCL is a configuration language for infrastructure as code.

Lua is a lightweight scripting language for game development and other applications. Crystal is a fast and expressive language for building web applications. As said before, Rust and Kotlin are already popular programming languages, but are expected to gain even more traction in the coming years.

How to Choose the Right Programming Language

Choosing the right programming language depends on your goals, interests, and career aspirations. If you are interested in web development, JavaScript and Python are the best choices to start with. However, if you are considering a career in mobile app development, Swift and Kotlin might be better options.

For scientific computing, you should consider learning Julia and Python, for example. If you are interested in system software development, C++ and Rust are good choices.

When choosing a programming language to learn, it is also important to consider the learning curve, resources available, and community support. Some programming languages have a steeper learning curve than others and may require more time and effort to master.
