Top 5 Programming Languages To Learn in 2021


Python has been the only language that has grown steadily over the past five years. It’s a general-purpose language, so someone wants to learn a single programming language in 2020 and wants to cover more areas of software development than Python could possibly choose.

Its high-level integrated data structures, combined with dynamic typing and dynamic binding, make it very attractive for rapid application development, as well as for use as a scripting or pasting language to connect existing components between them.

Python’s simple and easy-to-learn syntax emphasizes readability and therefore lowers the cost of program maintenance. So for me, Python will be the most important language for machine learning and data science among the top 5 programming languages.


JavaScript was originally created to make web pages come alive. Programs in this language are called scripts. They can be written directly into the HTML code of a web page and run automatically when the page loads.

The popularity of JavaScript can be attributed to the growth of the popular JavaScript library and framework such as node.js etc. JavaScript is the language of the dynamic website and it will be the best for years to come due to its active development, support from Mozilla, and libraries and frameworks.

So, if someone wants to be a Front End Developer or a Full Stack Developer, JavaScript is a must-have among the 5 best programming languages.


Java was up but down in 2019, which is why Kotlin could gain popularity on the Android platform. Java is a good choice for a programming language, but now it’s under Oracle and Google is promoting Kotlin so it’s in the conflict zone. In fact, still, a large number of companies are using Java and will continue with Java because of its developer base, framework and legacy application.

Java applications support the Write-Once-Run-Everywhere paradigm. This means that you can develop and compile a java program in one system and run the compiled code in any other type of operating system.

So, if you are looking to become an Andriod developer or a back end developer, Java will be a good choice for you among the top 5 programming languages.


C is one of the earliest programming languages, and most newer languages ​​use C / C ++ as their code base, such an example would be R. Working with C / C ++ requires a good understanding of the fundamentals of programming. programming.

Even though C / C ++ is among the more complicated aspects of programming languages ​​for data science newbies due to its low-level nature, it is increasingly used to create tools that you can use for data science. Data Science.

If you think that C and C ++ are not popular now and that it won’t give you a good future, then you are really wrong. I agree that the popularity of C and C ++ is declining, but that’s because of newbies who find an easy way to program. 

So it never means that if you are not able to learn a programming language just because of its difficulty, that language will die. C and C ++ developers always get the highest packages. So learning C or C++ are the best languages out of the top 5 programming languages, if you want to develop operating languages and new programming languages.


Kotlin was introduced in 2011 by JetBrains Team, but few programmers paid attention to it until Google announced it as the official language of Android development on Google.

Kotlin is the future of Android development, what Android Java for Android does, Kotlin can do in a simpler and better way, so if you are curious to gain knowledge about Android development, you need to purify your abilities, then you should start learning Kotlin.

So these are the 5 best programming languages you should learn in 2021. Hope you liked this article on the 5 best programming languages. Please feel free to ask your valuable questions in the comments section below.
