Programmer should constantly upgrade their skills according to the market demand, be it learning a new language, tool, or library, or improving an existing one.
However, there are other factors that facilitate the decision to pick up a new programming language, including the project specification, team needs, and future viability. On the other side, many programmers want to learn a programming language that gives them the best future opportunity to earn more.
Java is one of the most adopted programming languages, used by nine million developers and running on seven billion devices globally. It was designed to be a language that could run on any device and that is why it is used for software development for computers, smartphones, and even smart TVs.
C was designed by Dennis Ritchie and is the first proper programming language that offered all the tools to create complex applications. It’s heavily used in kernel and OS development — if you’re using Windows, Linux, or Mac, C is working under the hood. C is also used as a starting language to teach programming in many colleges and online courses.
Bjarne Stroustrup designed C++ in 1983 to improve the C programming language, and he completely succeeded in doing so. C++ is extremely popular in system-oriented development projects, and it’s heavily used in game development and animation. Big companies use C++ constantly to improve the state of their system and make it more efficient.
C++ is a must-learn programming language for a programmer who is dealing with system-level development. With over three decades in the market, it has only grown. C++ is hard to learn, but rigorous practice does help. C++ is also an excellent way to learn computing or programming.
Python is a widely used high-level, general-purpose and dynamic programming language. It’s “the” language of the moment and the chosen starter language in university courses around the world. It has the biggest year-on-year job demand growth of any language, stated by the Stone River Academy.
Python worldwide has grown the most in the last 5 years (7.0%), following Java in popularity, as stated by PYPL.
Dating since 2000, C# is a new programming language designed by Microsoft for a wide range of enterprise applications that run on the .NET Framework. Still in the shadows of PHP and Java, C# has experienced a growing popularity every year.
As an evolution of C and C++, this language is simple modern, object-orientated and functional.
PHP is the most popular language used to write various web applications, having a more significant edge over its competitors as it is open source and stable. PHP is ranked 6th in the TIOBE programming community index and has grown with 43% on GitHub by a number of pull requests in the last twelve months.
Most recruiters over the world look for PHP developers to build dynamic websites which are responsive and interactive as well.
7. Visual Basic .NET
Visual Basic .Net is a simple, modern, object-oriented computer programming language developed by Microsoft. Visual Basic .NET is a fast and easy way to create .NET-based applications, including XML Web services, ASP Web applications, desktop applications, and mobile applications.
Visual Basic .NET has many new and improved features that make it a powerful object-oriented programming language, ranked at no. 7 in the TIOBE programming community index and continuously improving.
9. Delphi /Object Pascal
Delphi is the choice for developers wanting the power, readability and flexibility of the Modern Object Pascal language, coupled with native compilers and component libraries for fast single source code development on Windows, macOS, iOS, Android and Linux.
Go is a free and open source programming language created by Google in 2007. In 2016 its popularity skyrocketed because it emphasizes simplicity, high performance, efficiency and built-in support.
Keeping in mind that many start-ups have made it their language of choice, 2017 is guaranteed to be the year when more developers start using Go.
