1. Swift
    Swift has become more popular than Objective-C in recent years. It is a programming language for developing native apps for iOS or Mac OS. It can also be said to be the programming language with the greatest potential to change the future. Native apps have been found to outperform cross-platform hybrid apps, with the SpriteKit engine making it easier to create 2D games. In fact, Swift builds on the successes of C and Objective-C, but without the limitations of compatibility.
  2. Go
    Go is the language of 2009, the era of multicore processors, whereas languages like Python and Java emerged in the years of single-threaded development environments. That’s why Go takes into account multitasking and works with it. Instead of the well known Threads, which in most languages occupy a lot of memory (for example, in Java, it is 1 Mb per thread), in Go there is a goroutine that “eats” only 2 Kb of memory. You can create as many as a thousand or a million horoutines and it will have practically no effect on the application’s performance.
  3. PHP
    PHP is used everywhere thanks to WordPress. 80% of sites with over 10 million users use PHP. Examples of such sites would be Facebook and Wikipedia. PHP does not have any strict rules for writing code, and it is flexible in solving various problems. PHP is a great choice for web developers as it is the server-side scripting language for both Worldpress and Facebook.
  4. C++
    C++ was created in 1983 as an alternative to C and immediately gained a well-deserved popularity. Its main feature is predefined classes. Microsoft Windows and Google Chrome are the most famous examples of C++ projects. Adobe and Amazon projects can add to this list. This programming language remains in demand to this day because it has a powerful toolkit that can be adapted in different areas such as finance, banking, games, communications, electronic payment systems, retail, and more.
  5. Python
    This language is the future, and that’s no exaggeration. Firstly, it’s easy to understand and use: Python is gradually being introduced into the curriculum, replacing outdated Pascal and other “wooden” languages everywhere. Secondly, it’s neural networks: if a developer gets into machine learning, he immediately turns his attention to Python. Why? This language has become rich with a sufficient number of libraries focused on neural networks (Ruby loses out in this regard).
  6. JavaScript
    According to statistics compiled by the Stackoverflow (Stack Overflow Developer Survey) which audited more than 64,000 developers in 173 countries, JavaScript has become the most used programming language in the world. It provides the ability to create interactive websites and is one of the main web technologies along with HTML and CSS, since most browsers can use JS in one form or another.
  7. Java
    Java is one of the most practical programming languages to learn. Its popularity cannot be overestimated, as most (90%) of Fortune companies use Java to develop backend systems and desktop applications. Cross-platform is achieved thanks to the JVM.
  8. C#
    Developed by Microsoft, this multi-paradigm general-purpose programming language has been used to develop applications on the Microsoft platform. C# is an object-oriented language used to develop applications based on .NET frameworks. And, if that’s your market, C# is the best language for building native applications for the Microsoft platform. It is also the recommended language for game development using the Unity Game engine.
  9. Kotlin
    Kotlin is rapidly evolving and has several advantages. Among them:

conciseness of the programming language;
compatibility with Java;
is supported by Google;
a growing community.
It is possible that soon applications for Android devices will be written exclusively in Kotlin, so those wishing to develop in the direction of mobile development are strongly encouraged to take a closer look at this language.

  1. Rust
    In 2016, Rust took first place in the “what developers love most” poll on Stack Overflow. Rust was the programming language that developers really appreciate (79.1% of the votes). The open-source development language, developed by the Mozilla Foundation, works as a low-level language.

What’s most interesting here is that Rust emphasizes secure code (i.e., objects are managed by the programming language from start to finish). While it has no inheritance, it has traits and structures. It is universal and rests on three pillars: ergonomics, speed, and safety.
