Top 10 programming languages 2023

As we have been observing, the demand for specialists for the Software Engineer position has been growing for some time now. All indications are that this upward trend will continue. Research conducted by BLS underscores this vision. It shows that by 2028 the number of programming jobs will increase by 21%. As a result, the number of people interested in expanding their knowledge of this skill area in IT is also growing all the time.

1. Python


At the top of our list is invariably Python. It is a versatile programming language, created 30 years ago by Guido van Rossum. This technology is used in the development of applications such as Instagram, Pinterest, Disqus, Uber, Reddit, Dropbox, Spotify, Google Search, Youtube, and many others. That’s why programmers who know this programming language are highly sought after by IT recruitment agencies. The fact that Python was the most popular programming language in the TIOBE Index in 2020, 2021, and 2022 also testifies to the very high interest in it. There has been a very strong upward trend for several years, and there is no indication that this trend will change dramatically in 2023.

Why did Python take first place?

  • According to Stack Overflow, Python is the most popular backend programming language and the most desired technology.
  • It is also the most popular language for professionals in the position of Data Scientist or Machine Learning Engineer.
  • It has many followers and a huge community that helps each other and supports each other with knowledge.
  • Although Python is now 30 years old, it is still gaining popularity. Just take a look at the Tiobe INDEX:
  • It provides various capabilities. It enables the development of applications, AI software, games, websites, and more.
  • Python has many fans because its syntax is clear and easy to learn. As a result, learning this language is a common choice for novice programmers.
  • The time required to test code is significantly reduced, thanks to interactive language features such as running a quick code test. According to Adam Basek – Test Manager and co-creator of the 4_testers course, Python is one of the best programming languages for beginners’ manual and automation testers.

2. JavaScript


In second place is JavaScript – the king of the frontend. It is a programming language used to create websites. According to the Stack Overflow Developers Survey 2022, it is the most popular and in-demand programming language in 2022. The huge demand for JavaScript has remained relatively constant since the beginning of 2021.

Like Python, JavaScript has a strong community and many ready-made libraries and frameworks that make the language easy to work with. This programming language has no competition if you need to create a frontend for your website, application, or software. It’s very easy to learn because it’s a higher-level language, so it doesn’t require dealing with a lot of intricacies in code. You can learn the basics of the language in a few months and build an application yourself or start creating simple programs. What’s more, JavaScript works well with other languages and can be used in many different applications. It is also a great platform when building dynamic elements on a page.

3. C / C++


C is one of the oldest programming languages, from which other languages such as JavaScript and C# are derived. In addition, the C++ language can be considered an extended version of C.

Both languages have high performance, so they are widely used to develop various applications. They are considered universal languages. This means that they can be compiled for many systems. Programmers love these programming languages for being very fast and efficient.

According to the TIOBE Index, the C++ language has seen an increase from 2021 and is now – after Python – the second most popular programming language.

4. Go

Go język programowania

If you’re thinking of learning a new programming language to upgrade your skills, then Go might be a good option. This technology was developed by Google in 2007 and has been used to create web applications and APIs. Although Go has not achieved a growth rate on the same scale as the previously described languages, it can still be counted among the highly sought-after skills.

It is an easy-to-learn, general-purpose programming language with a clear syntax that makes it easy to write simple, reliable, and efficient software. It is ideal for creating web servers or full-fledged machine-learning packages. In terms of functionality, there are almost all the features typical of C and C ++, but it does not have a complex syntax.

It is still one of the highest-paying technologies and a sought-after backend programming language. This means that if you learn this programming language, you will have no trouble finding a well-paid job. According to Stack Overflow, the median annual salary is around $89,000.

Go, like Python, is used to create systems based on artificial intelligence, so its popularity is likely to grow.

5. Java


Until a few years ago, Java would probably have topped our list. This programming language was declared the language of the year in 2005 and 2015. However, its popularity is declining year by year, as evidenced by the TIOBE INDEX:

However, Java is still a stable language that is supported by many large corporations. It is used by companies such as NASA, Netflix, Spotify, LinkedIn, Uber, Amazon, and many others.

The language is currently used in the development of mobile applications, websites, and even Big Data. It is the primary programming language for Android devices, so the demand for skills related to it will continue to be high. As of today, it is the sixth most popular technology according to Stack Overflow.

6. C#

C# język programowania

C# is a high-level, object-oriented general-purpose programming language. It was developed as Microsoft’s answer to Java. C# is integrated into the .NET platform, both the framework and the management environment.

C# is a technology created to create and develop applications for Windows systems. Since the .NET framework started to be used on Linux and Mac, it is possible to develop native software in this language for any platform.

You can use this technology to develop Windows applications, video games, anti-hacking software, mobile applications, VR, and much more. Many applications have been built in C#, including simple computer programs and large web portals. It is used by global giants such as Microsoft, Slack, and Pinterest. In the Stack Overflow 2022 report, the C# language ranked right after Java at number 7, and Tiobe ranking at number 5.

7. Rust

Another valuable programming language in 2023. It’s not as popular or sought-after among programmers, but it certainly deserves attention. According to Stack Overflow 2022, Rust is the most favorite programming language for the seventh year in a row, with 87% of programmers saying they want to continue using it and 17% want to develop in it.

Its main purpose is to program low-level systems, but Rust still focuses on security and speed. The main focus is on code security, so programs can’t access certain parts of memory they don’t use. However, it’s not a language for beginners, it’s difficult to learn, but the skills gained will definitely pay off in the near future. This is also evidenced by the TIOBE Index, in which the Rust language records a significant upward trend.

8. Ruby

Ruby język programowania

Ruby is an interpreted and fully object-oriented programming language. It was developed in the 1990s and is considered easy to learn. As a technology with a simple syntax, it is often used for scripting, text processing, and prototyping new applications.

Its significant advantage is the massive web frameworks and applications written in the language, such as the well-known Ruby on Rails. Ruby is a stable and popular language used by Twitch, Shopify, Starbucks, and Tumblr. What’s more, it is the sixth highest-paid programming language in the world.

9. Kotlin


Kotlin is a programming language that is part of the JVM family. It is considered by most programmers to be a concise language and easy to read and maintain. It features a safe and intelligent compiler and can run on a variety of systems. The moment when interest in the language surged was certainly in 2019. This happened because Google then announced Kotlin as the current preferred language for Android apps. So, in conclusion, Google apps are based on Kotlin. If you are interested in Android app development and want to work in this field, then learning Kotlin in 2023 may be the right choice.

Despite the fact that this programming language has a smaller community of programmers than Java, it is considered much more well-liked (more than 63% of programmers said they love this language). In addition, it can be noted that it is still very profitable.

10. Swift


Swift is a programming language that was created in 2014 by Apple. It replaced Objective-C, which was previously used by the company. It is mainly used in macOS, iOS, and Linux devices. Its syntax is similar to Java and C# and allows you to write apps for watches, tablets, computers, smartphones, TVs, and servers. Interestingly, iOS apps generate the most revenue in the mobile app market.

Apple is still one of the leading brands, so Swift will continue to be a big player this year. To learn Swift, a time commitment is necessary, but previous experience with other languages is not required. According to TIOBE, Swift’s popularity saw a decline in 2022, however, it is still a technology worth learning in 2023.
