Which Programming Languages Will Dominate 2023? A Data‑Driven Ranking

If programming languages vanished, the online services we rely on daily would disappear, underscoring their critical role in the digital world. With a growing number of languages, developers should pay attention to the most sought‑after technologies in the IT market.

The IT industry’s demand for technical experts shows no sign of waning and is expected to continue for at least the next decade. Whether you are considering learning a new language or already work in IT, the 2023 popularity forecast can guide your decisions.

Research indicates that programming jobs will increase by 21% by 2028, driving more people to expand their IT skill sets.

1. Python

Python is a general‑purpose language created by Guido van Rossum 30 years ago. It powers applications such as Instagram, Pinterest, Uber, Reddit, Dropbox, Spotify, Google Search, YouTube, and TikTok, making Python developers highly sought after by employers.

Python topped the TIOBE index in 2020, 2021, and 2022, showing a strong upward trend that is expected to continue in 2023.

Why is Python #1?

According to Stack Overflow, Python is the most popular backend language and the most in‑demand skill.

It is the preferred language for data scientists and machine‑learning engineers.

It has a massive, supportive community.

Even after 30 years, its popularity remains high.

Python’s versatility supports applications, AI software, games, and websites. Its clear syntax makes it a favorite for beginners and for rapid testing, reducing development time.

2. JavaScript

JavaScript, the “king of the frontend,” is used to create websites and was the most popular language in the 2022 Stack Overflow Developer Survey. Its extensive libraries, frameworks, and large community make it easy to learn and apply across many platforms.

JavaScript works well with other languages and is essential for building dynamic page elements.

3. C / C++

C is one of the oldest languages, and many others (including JavaScript and C#) derive from it. C++ extends C with object‑oriented features. Both offer high performance and are used for a wide range of applications.

According to the TIOBE index, C++ has risen since 2021 and is now the second most popular language after Python.

4. Go

Developed by Google in 2007, Go is a simple, general‑purpose language with clear syntax, ideal for web services, APIs, and even machine‑learning packages. It offers C‑like performance without complex syntax and ranks among the highest‑paid backend skills, with a median salary around $89,000.

Go is also used for AI systems, suggesting continued growth.

5. Java

Java has long been a top language, recognized as “Language of the Year” in 2005 and 2015. Although its popularity has slightly declined, it remains a stable choice used by NASA, Netflix, Spotify, LinkedIn, Uber, and Amazon.

Java powers mobile apps, web services, and big‑data solutions, especially on Android, keeping demand high. It ranks sixth in the latest Stack Overflow popularity list.

6. C#

C# is a high‑level, object‑oriented language created by Microsoft as a counterpart to Java and integrated into the .NET platform. It enables cross‑platform development for Windows, Linux, and macOS.

Developers use C# for Windows applications, games, security tools, mobile apps, and VR. Major companies like Microsoft, Slack, and Pinterest rely on it. In the 2022 Stack Overflow report, C# ranked seventh, and TIOBE placed it fifth.

7. Rust

Rust, though not the most popular, has been the most loved language for seven consecutive years in the Stack Overflow 2022 survey, with 87% of developers wanting to continue using it.

Designed for low‑level system programming, Rust emphasizes safety and speed, preventing many memory‑related bugs. It has a steep learning curve but offers high rewards, and its TIOBE ranking shows a clear upward trend.

8. Ruby

Ruby is an interpreted, fully object‑oriented language created in the 1990s. Known for its simple syntax, it is popular for scripting, text processing, and rapid prototyping.

Ruby on Rails powers platforms such as Twitch, Shopify, Starbucks, and Tumblr, making Ruby one of the highest‑earning programming languages.

9. Kotlin

Kotlin, part of the JVM family, is praised for its concise, readable, and maintainable syntax. Google’s 2019 endorsement of Kotlin as the preferred language for Android apps sparked a surge in interest.

Developers appreciate Kotlin’s safety features and attractive salaries, despite a smaller community than Java.

10. Swift

Swift, introduced by Apple in 2014 to replace Objective‑C, targets macOS, iOS, and Linux. Its syntax resembles Java and C#, enabling development for watches, tablets, phones, TVs, and servers.

iOS apps generate the highest revenue in the mobile market, and Apple’s strong brand ensures Swift’s continued relevance. Although its popularity dipped slightly in 2022, Swift remains a valuable skill in 2023.
