What language to learn to become a sought-after developer? Catch the TOP 7 programming languages ​​you need in 2020.

We live in a digital age where information technology is developing rapidly. Nowadays, the demand for learning programming is growing rapidly. Development is divided into small specialties, including systems programming, game development, mobile application design, and web programming. If you want to study development on your own or take a suitable position, pay attention to the languages ​​that are popular today.

7 Best Programming Languages ​​you Should Learn In 2020

Programmers choose from a wide variety of languages, from JavaScript to Python software development. Some have only skyrocketed in popularity in recent years: Python programmers, for example, are a fast-growing niche, while others are in sharp decline.

Since programming languages ​​are at the heart of the product, it is important to understand why developers use specific languages ​​and what the total benefits each will bring to your software.

For example, Java, C ++, and Python developers receive different benefits. So which language is the best for your project? Consider the main programming languages ​​for 2020.

1. Python

Python continues to gain traction. In fact, according to Stack Overflow, it is the only programming language that has shown a steady upward trend in popularity over the past five years.

The TIOBE index predicts that it will soon overtake Java and C. So if you choose Python as the development tool for your next project, you are not alone.

Python developers learn to write code quickly and easily because of the simplicity of the language. It is a general-purpose language, that is, it is used to create anything. It’s also free and open-source and provides a bunch of libraries.

Machine learning, artificial intelligence, Big Data, and robotics rely on Python. The big challenge of software development – cybersecurity – is also handled by Python. Also, in 2019, Python is the most popular language for introductory courses at universities.


  • Transparent form, clear structure, short syntax.
  • Available on all platforms of UNIX, MS-DOS, Mac OS, Windows and Linux operating systems, and other Unix-like operating systems.
  • Strong compatibility with Unix, hardware, third-party software with a huge library.
  • With its high processing speed, Python is suitable for writing both small scripts and extremely large programs such as Blender 3D.


  • No access modifiers such as: protectedprivate, and public.

2. Java

Java is the most famous programming language. It was released in 1995 and remains popular to this day, although, as mentioned above, Python developers may soon overtake Java programmers in numbers. This general-purpose language is widely used for developing mobile applications and games, especially for Android.

Java ranks among the top-paid programming languages. Java is used by 9 million developers and 7 billion devices worldwide. It is an essential platform for writing commercial software applications. As of November 2019, Java is ranked # 1 in the TIOBE programming community, making up 16.25% of the top 50 programming languages.

  • Cross-platform.
  • Cool enterprise development frameworks (Java EE and Spring stack).
  • Low entry threshold for a beginner.
  • Reflection in the language itself, thanks to which such powerful libs as Hibernate, Jackson, etc. appeared.
  • You can write for android.
  • Can be integrated with other JVM languages, i.e. Scala, Kotlin, Groovy.


  • Performance is slower than native languages, despite techniques like JIT compilation.
  • Lots of boilerplate code.
  • The frameworks are heavy and complex in the configuration. For Spring, they even wrote Spring Boot – in fact, a framework over a framework.

3. JavaScript

The number of JavaScript users has grown lately. It now ranks first in popularity according to the 2019 Stack Overflow Developer Survey. It is an object-oriented language that is responsible for creating interactive, dynamic web pages, including features such as animation and scaling. JavaScript has a large community and a lot of support, libraries, and frameworks.



It is the # 1 language on GitHub in terms of pull requests. A ton of modern websites uses JavaScript today.

When you run JavaScript in your browser, you are not loading any additional software. And also the language is very accessible for beginners. Due to its simplicity and speed, many startups and tech companies use JavaScript today.


  • Easy to learn, also due to the fact that it has a few low-level concepts.
  • A huge community, a large number of materials and courses are freely available.
  • It develops very quickly, it becomes more convenient, there are many add-ons like Typescript.
  • JavaScript runs on any operating system with a browser that supports it.


  • There is too much freedom in coding and it is easy to make mistakes because there are no hard and fast rules, no compile-time checking, no types, etc.
  • Poor security, inability to hide the code.
  • WTF JavaScript is about him too.

4. C++

C ++ has gained popularity among developers around the world and often becomes the basis for learning other languages. This powerful programming language with a history of over 30 years is still actively used in game development.

A lot of popular applications are written in C ++, including Google Chrome, Photoshop, PDFReader and others. Microsoft, PayPal and LinkedIn continue to use it. If you are a professional C ++ programmer, you have every chance of getting a top-notch salary from big guys like Google or Facebook.

In current realities, C ++ is still actively improved by the community. More and more language updates are being made such as C ++ 14, C ++ 17 and the upcoming C ++ 20.


  • Supported by the community, most programmers start learning computer science with C / C ++.
  • It is used in many large projects, including high-load ones.
  • High memory control, the ability to improve the security and performance of the application.
  • Inherits the traditional strengths of the C language, such as flexibility or compatibility with hardware devices.


  • There are often complex syntactic constructions that are sometimes difficult to read.
  • If you do not require high performance in the application, C ++ is not needed, because it is easier to use the same Python with numerous third-party modules that will greatly simplify and speed up development.

5. C#

For developers who know Java, learning C # is relatively easy. It is relatively young, released in 2001, but shows a positive momentum with a growing community and support. C # is an object-oriented programming language developed by Microsoft. C # runs on the .NET platform, which is used to write desktop applications and games on Windows. Although C # is also suitable for mobile application development. This language is built on the C and C ++ languages, but it is easier to use.

C # has the same syntax as Java. In addition, the Xamarin platform, written in C #, is used to develop applications for devices with a variety of operating systems (Android, iOS, and others). C # is commonly used in virtual reality, 2D, and 3D games.


  • C # is an easy language to learn.
  • C # has a huge online community, and the Internet is full of materials and courses to learn.
  • Creation of cross-platform software.
  • Application development for Android and iOS.

6. Swift

The Swift and Python developers are two of the fast-growing segments of the programming industry. Released in 2014, Swift is the language of choice for Apple’s apps and software. So if you want to develop products that are compatible with Mac OS or iO, learn Swift.

Despite its age, it has already proven itself to be a highly practical and functional language, especially when compared to previous Apple-related languages. It is also easy to maintain and uses very little memory.

7. PHP

Software development in JavaScript and Python has become much more widespread than PHP, but the language is still popular. PHP is a general-purpose language and is primarily used for server-side programming.

WordPress works with PHP as well as big companies like Facebook, MailChimp, and Slack. Some useful features include quality debugging and an extensive ecosystem. PHP is easy to learn too.


Now you know which languages ​​will be in demand in 2020, and you will see them everywhere in the coming months.

Given your personal and team preferences when choosing one language, keep in mind that each offers advantages in achieving different goals. For example, for mobile and desktop applications, turn into a Python developer. When you need interactive elements on the site, most likely the choice falls on JavaScript. C # is a good option for making games.

However, no matter which language you choose, know that the seven on this list offer clear benefits and help you create great code for your project.

Also, do not ignore and learn other languages: this predisposes to the convenience of work. In fact, the development of information technology and the latest trends are pushing you to learn more and more programming languages ​​in order to become a multilateral developer.
