One can argue about the growing popularity of Java. However, the fact is that Java still and will continue to maintain relevance and high demand due to its many efficient features.

Mainly used for:

Android application development
Web development
Software
Finance and e-commerce

5. Kotlin

Android is the world's highest selling and most used operating system. Google has announced Kotlin as the main language for Android development. Therefore, it is logical that without Kotlin there would be no list of the best programming languages.

It is worth noting that it is a cross platform universal coding language that can provide you with full interoperability with Java.

Kotlin is increasingly used in server-side development, Web and cloud development, data science and other fields.

This is because it adopts the best practices of other object-oriented languages and is easy to learn. Therefore, bringing Kotlin into your arsenal in 2021 will greatly help you further develop or start your developer career.

Mainly used for:

Android application development
Software and network development
Data science
Server side development

6. PHP

The advantage of a towering server-side application builder is that almost 80% of all websites use PHP. Technology giants such as Yahoo, Wikipedia and Facebook also attach great importance to PHP.

Its grammar is very clear and easy to learn. It also provides you with many powerful frameworks, such as Laravel, to make your life easier. In addition, PHP is compatible with all well-known databases.

PHP also provides a number of automated tools for deploying and testing applications. In addition, PHP developers work day and night to establish their position from server-side scripting languages to general-purpose programming.

Mainly used for:

Back end network development
Server script

7. C#

C # (pronounced "CSharp") is a programming language built by Microsoft and inspired by the C programming language. However, C # is more advanced, more dynamic, and more compatible with NET framework is fully integrated.

Most developers like C # to use the Unity game engine to produce 2D and 3D games. Well, it is also very common in desktop and mobile application development.

In addition, C # is even convenient in Web development. You can find noteworthy C # Web development examples on the server side of Bing and Visual Studio.

At present, it still ranks fourth in the popularity index of PYPL. The demand and growth of C # as a programming language will certainly expand over time. Therefore, if you study C # in 2021, you will neither be late nor lack of money.

Mainly used for:

2D and 3D game development
Web development
Desktop and mobile applications
virtual reality
