Which is the top programming language

Top programming languages ​​for 2020

According to Wikipedia, there are nearly 700 programming languages ​​worldwide and it is highly likely that you have never heard of some of them. In this article we would like to highlight the most important programming languages ​​for 2020.

The most widely learned programming languages

To see the popularity of programming languages ​​among beginners and professionals looking to build their personal technology stack further, let's show you the PYPL Index (http://pypl.github.io/PYPL.html). PYPL (PopularitY of Programming Languages) shows how often people search for hands-on introductions and learning courses on Google.

As you can see, Python is the most preferred language right now, followed by all the top languages ​​you've definitely heard of. Compared to the previous year, an increase in popularity can only be observed in two languages: Python (+ 4.1%) and JavaScript (+ 0.1%). All other languages ​​mentioned lose their position: Java (-1.8%), C # (-0.1%), PHP (-1%) and C / C ++ (-0.2%).

22 other programming languages ​​have a significantly lower proportion of the languages ​​sought. However, there are two languages ​​that show significant growth in popularity: Kotlin (+4 positions) and Dart (+7 positions). We believe that they will continue to attract more attention and should be considered for learning.

The most commonly used languages

Now let's look at the languages ​​that are actively used for software development. To do this, let's look at this statistic from GitHub (https://madnight.github.io/githut/#/pull_requests/2020/2), which provides relevant information on the popularity of languages ​​over the past 5 years by repository contributors .

While it is the most popular language to learn and outperforms Java, Phyton is only the second most popular language. JavaScript remains the undisputed champion year after year and we are sure it will continue to be number one.

We would also like to mention the use of the languages ​​that are not as popular as those mentioned above but show significant growth in popularity compared to last year. Here are the 5 languages ​​we'd like to highlight: Dart, Rust, Kotlin, TypeScript, Go.

Another source to look out for - the TIOBE index (https://www.tiobe.com/tiobe-index/). It is updated every month and shows the popularity of programming languages ​​based on the number of learning courses, experienced developers and other related data provided by top search engines (Google, Yahoo, Bing, Amazon, Youtube, etc.).

The table shows a different picture that the most popular languages ​​are still there: Java, JavaScript, C, C ++, C #, Python and PHP. Swift is proving to be the fastest growing in terms of popularity. Swift is proving to be the fastest growing in terms of popularity. It can be called an "Objective-C killer" as it was released by Apple to replace Objective-C (its popularity has dropped significantly - it can be seen in the first graphic). Swift is easy to learn because of its simple syntax and is mainly used for developing apps for iOS and Mac platforms.

Top 10 programming languages ​​for 2020

Taking into account all of the information mentioned and in combination with our 20+ years of experience in software development (https://scand.de/), we would like to highlight the ten most important programming languages.

# 1 JavaScript

JavaScript is the number one language that is used. It is a high-level, dynamic, multi-paradigm programming language that will be the most popular in the world for many years to come. Mainly it is used to develop interactive and feature rich web applications, but it can also be used to create other software that runs anywhere: servers, browsers, mobile devices, microcontrollers, etc.

# 2 python

Python is now the most learned and will soon increase its popularity in use. Considered the easiest language to learn because of its elegant and simple syntax, it is used in programming teaching and is widely used for machine learning (ML), deep learning (DL), data science, and math, statistics, and computer science. Python is both simple and powerful, and enables the optimization of the development process of robust applications: web or mobile.

# 3 Java

Despite having similar names, Java has little in common with JavaScript. It is an object-oriented, interpreted programming language that was the first to make it possible to write your code once and execute it anywhere. This language can be used for developing applications of all sizes, both web development and mobile development, as well as enterprise-level application development and working with big data.

# 4 PHP

With a huge open source community and widespread use from such industry giants as Facebook or WordPress, PHP remains in demand, although its popularity is slowly falling. This is a general-purpose dynamic scripting language that was created for building dynamic web applications.

# 5 C ++

C ++ appeared as an improved version of the C language that introduced object-oriented functions. It offers many compilers and libraries to create powerful and reliable solutions that can handle high performance and extensive functionality. C ++ adapts easily to ecosystem or hardware changes and is a perfect option for cloud computing as well as game development. It is one of the most difficult languages ​​to learn.

# 6 C #

C # is a multi-paradigm programming language created by Microsoft to run on the .NET framework. It combines the code compilation as in C ++ with a Java-like syntax. C # enables fast and feature-rich applications of any complexity to be developed across multiple domains: native apps for iOS and Android (using Xamarin), desktop apps for Windows or Linux, complex web systems, etc.

# 7 darts

Dart was published by Google in 2011 and is currently a champion with growing popularity (+ 532% per year). This language can be said to be user-centric because it focuses on developing top notch user interfaces while providing great performance for all types of platforms and devices. Dart is widely used with Flutter, which is Google's widely used UI toolkit, and allows you to create beautiful and easy-to-use web and mobile applications.

# 8 Rust

Rust is another programming language that is rapidly growing in popularity (+ 235% per year). It is used to build VR applications, game engines, operating systems, etc. Because Rust is fast and memory efficient, it's the perfect choice for powering performance-critical solutions and running them on embedded devices.

# 9 Kotlin

Kotlin is another modern, general-purpose programming language (it was released in 2015) that is becoming increasingly popular. It runs on JVM (Java Virtual Machine) and enables the use of a large number of Java libraries. Kotlin has much simpler and cleaner code than Java and offers developers productivity similar to Python. Because of all of these significant advantages, it is now the primary language for Android app development.

# 10 TypeScript

TypeScript is one of the fastest growing open source languages, calling itself "JavaScript that Scales". It shares the same syntax as JavaScript, which makes learning as easy as ABC (for anyone who already knows JavaScript) - this is one of the reasons TypeScript is being adopted so quickly by the industry. Another reason is the expanded functionality that software developers can use to create larger-scale solutions.


The core idea of ​​the variety of programming languages ​​is that each task can be solved based on different options and approaches. Each software solution can focus on its specific goals and achieve them in different ways. Therefore, it is important to understand the capabilities of each tool and analyze its potential to meet specific business needs.
