top 10 programming languages to learn in 2021 for free online


1. JavaScript

JavaScript is another language which is in high demand at the moment, but it is not to be confused with Java! Java is a programming language while JavaScript is a scripting language. It is relatively easy to learn but perhaps not as easy as something like Python. It runs on every single platform and is already in your browser for you to start learning which means you do not need to install it. If you want to build anything for the web then JavaScript must be on your list of programs to learn.

You can start using JavaScript straight away to start building websites and games for the web. It is one of the fundamental technologies which the web we know of today is built on. It is dynamic and is flexible to use on object-oriented programming. It derives much of its syntax from The C Language (discussed below).

Though the language is primarily known for adding responsive elements on web pages it has a wide range of applications such as in web development, game development, mobile application development, and many more. Moreover, the language is being used for both – Front End Development and Back End Development. Also, its compatibility with some prominent frameworks like React, Vue, Node, etc. makes it more preferable among the developers. As there are millions of websites already existing over the web that are heavily relying on JavaScript and on top of that, looking at the demand & dominance of the language, it won’t be wrong to say that JavaScript will rule in 2021 as well!

2. Python

Python is one of the most widely-used high-level programming languages. This is mostly because it is simple, readable and you can use fewer lines of code to express a concept than you would have to with other languages. It is a scripting language which allows you to produce a lot of code in short periods of time.

It is opensource and free and there are a lot of tools and documentation available for learning Python. There are some great official tutorials which are easy to follow and there is less of an emphasis on syntax which would suit beginners. It is a good stepping stone for moving on and learning other object-oriented languages.

As per the RedMonk Ranking report for the year 2020, Python outranks JAVA to become the second most popular programming language. The language has experienced tremendous growth of around 18-19% in the last 5 years. At the PYPL index, Python is ranking at the #1 position for December 2020 index. The language ranks among the most popular programming languages in several other renowned platforms also such as Stack OverflowGithub, etc. Also, the compatibility of Python with trending technologies like AI & ML makes it more preferable among the developers.

3. C/C++

There are numerous large tech companies with respectable compensation packages such as Adobe, Oracle, Microsoft, Nvidia, etc. that employ C/C++ developers. And learning C/C++ in 2021 is not only advantageous from a career perspective, it also makes it easier for you to learn other programming languages later.

Both C and C++ are occupying a considerable portion of the tech world and currently ranking at the top positions on various indexes. At the TIOBE index of 2020, C and C++ are ranking under the top 5 programming languages at first and fourth position respectively. At the PYPL index, C/C++ has seen an upward trend of around 0.1 % and is ranking at the #5 position.

If we particularly talk about C language, the general-purpose procedural programming language is majorly used in the development of low-level systems like operating systems, kernel development, and others. And many other programming languages inherit the properties of this particular language. On the other hand, C++ is an object-oriented programming language (primarily developed as an extension of C). The language is widely used in Game Development, GUI & Desktop applications, and Competitive Programming along with several other fields.


4. Java

One of the world’s most common programming languages is Java. In 1995, Java 1.0 was released on the Write Once Run Anywhere principle. It is an object-oriented, class-based language that is designed to be universal, meaning that it can be found on all platforms, operating systems and computers.

Java has been used for so long that there is lots of information about it on the web. This is ideal for beginners because this means that almost certainly any question you have has already been asked and answered by someone else in the Java community. It has an incredible toolset and great editors which let you know straight away if you have any errors. Java programming is a highly sought after skill and knowledge of it opens a lot of doors in terms of employment.

Many times it seems out that JAVA is losing its charm but when we look at the actual stats – every year JAVA ends up with a really good ranking that proves the particular language is still doing well and in-demand in the tech world. There are around 8 million JAVA developers across the world – maybe this number can help you to assess the demand & popularity of this particular language. Also, the language is enjoying a top-second position among all the programming languages in the ranking of TIOBE and PYPL. As per the RedMonk reports, JAVA is ranking at 3rd position below JavaScript and Python only.


5. Ruby

Ruby is a dynamic, object-oriented scripting language that is used in the development of websites and mobile apps. It is similar to Python in that it is simple and readable. It is usually focused on web-based applications. It is the language that powers their framework, Ruby on Rails, which is behind websites such as Twitter, Groupon and GitHub.

It is easy to learn with a helpful 20 minute quick start guide on the official Ruby website. It is straightforward and easy to read with a large community behind it of programmers willing to answer questions. There is a lot of documentation available as well as great resources which will help you to grasp Ruby from the very beginning.
