​Wondering what programming languages will be most popular in 2021?
What programming languages should you learn in the New Year?

1. Scala

As a functional programming language Scala offers a different paradigm than object-orientated programming, which will help to improve your thinking and code sense. Although there are many programming languages available, some of which feature in this list, Scala has been created based on the best practices of programming over the past 20 years and many people say that they found Scala easier to learn. Learning Scala will be most useful for Java Developers.

2. Python

Python is the fastest growing programming language. With well-built and reliable frameworks, it offers an intuitive and easy to learn syntax which makes it very popular. Python is one of the most widely used languages and is the most widely taught in schools and colleges around the world. Python is open-source and the preferred programming language for artificial intelligence, data science and machine learning.

​3. Java

Created in 1991, Java has been one of the most popular programming languages of the last two decades and it remains a firm favourite. Java is the preferred programming language to build robust, scalable, server-side application. Java has the tools, technology and community to enable you to build projects of any complexity. When learning Java you will only have to focus on application design and code structuring without worrying about system-specific details and memory management because JVM will take care of it.

4. Javascript

While you may be able to replace some of the other languages in this list, for example, you could replace Java with C++ or Python with Ruby, but you can not replace Javascript. It is the most popular language for web development because you can use it on the server side and the user interface. Knowledge of Javascript will help you to decide which feature should be implemented server-side and also which can be handled client side.

​5. C++

One of the oldest mainstream languages, many people say that knowing C/C++ makes you a better programmer and is a core basic that everyone should have knowledge of. The C is the most preferred programming language for system programming alongside Java. It is also one of the most important programming languages for game and web developers because of the high performance it offers.

6. Kotlin

Kotlin is a general purpose programming language, it can co-function with other functional programming languages like Scala and Java. Originally developed by JetBrains, Kotlin is used extensively for Android development, web development, desktop application development and server-side development. With the rise of android, we see the rise of Kotlin.
