Top 5 programming language to learn in 2020 -thebytewise

Programming is a skill that everyone should know at least the basics of in 2020. I mean why not programming languages and computer coding has made life simpler for us. Programming is an essential part of almost every organization from banks to the automobile industry to schools.

Whether you are aiming at joining a top-tier company or you are interested in a work from home carrier in programming, it is important to know what's trending in the industry. And sort your skills according to that.

So, we have established a baseline that programming is an essential skill to learn in the 21st century, in that view if you are a complete beginner you might be wondering "Where do I start?". In this article, we will discuss about the top 5 programming languages to learn in 2020.

Well before you start to learn any programming language it is really important that you at least know the basics of a computing system, well in 2020 it is highly unlikely that you don't know about a computer, this generation is basically born with a computer. So without getting any more into the new generation theory let's begin with the actual topic.

Top 5 programming language to learn in 2020

1. Python

Although this is a controversial topic for some people, Python is actually a very good point to start. It continues to be one of the best programming language every developer should know or learn. The language is easy to learn and relatively powerful. Python is even used by many fortune 500 companies like Google and Microsoft.

Python can be used for web development, Desktop applications, data science, machine learning, and a lot more. The possibilities are countless. And if you are aiming for a job this will be a great help to your resume.

There are tons of libraries available for example Django and Flask for web development and TensorFlow, pandas, and SciPy for data science applications.

Python has been around for a while now, and it really does make sense to learn it now.


  • Easy to learn

  • Great support and study materials

  • Widely used

  • Lots and lots of libraries

  • Basically an almost all-rounder language


  • It is a bit resource-heavy

  • sometimes it is hard to understand the code as it lacks braces, so the developer has to depend on indentation for code formatting. Although this is more of personal opinion.

  • Not suitable for mobile applications

2. Kotlin

Kotlin is a relatively newer language which was launched in 2011, it is a general purpose programming language. It is designed to be completely interoperable with Java. Also, Kotlin is now the official language for android development, it offers advanced features that developers primarily asked for. It combines object-oriented and functional programming features within it.

The effortless interoperation between Java and Kotlin makes android development faster and more efficient.

Kotlin addresses the major issues surfaced in Java, it is easy to learn, open-source, and a versatile language for android development. Many companies have started shifting from Java to Kotlin, several Java apps are even being re-written in Kotlin now.

As more and more companies start using Kotlin it is likely to replace Java completely. This makes it a very important language for Android development in the present and hopefully in the future as well.


  • Easy to learn

  • Addresses the problems of Java

  • Interoperable with Java

  • open source

  • Greatly values in the industry


  • Not many learning materials available as of now

  • People who already know Java are likely to prefer Java over Kotlin

3. C/C++

Although this a really old language, C/C++ is like the base plate of a lego set. Almost all low-level systems such as operating system, file system, Compilers for other languages, etc are written in C/C++. If you want to be a system-level programmer C/C++ is the language you should learn. This language is also used by competitive programmers as it is extremely fast and stable. C++ also provides an STL (Standard Template Library) which is basically a pool of ready to use libraries for various arithmetic operation, data structures, and algorithms.


  • Extremely fast and reliable

  • STL support

  • Rich function library

  • programs are easy to understand and more efficient

  • Forms a basic understanding for more complex programming language.

  • Offers low-level abstraction


  • Not the easiest to learn

  • No garbage collection

  • smaller standard library

  • complex syntax

  • no run-time checking

4. Swift

Swift is the programming language used to develop IOS application. As IOS devices are becoming extensively popular it is giving a tough competition to android. With the growing popularity of IOS Swift has also become a very popular language in the industry. Swift is also interoperable with objective-C.


  • Backed by Apple

  • Automatic memory management

  • Easy to add new features

  • Relatively fast

  • High level syntax (easy to understand)

  • Faster development process


  • Limited resources

  • Limited community support

  • Relatively new

5. R

R is one of the most commonly used languages for data analysis and machine learning. R provides a great framework and built-in library to develop powerful Machine Learning algorithms. R is also used for general statistical computing as well as graphics.


  • Ability to run smoothly in almost all operating systems

  • Open source

  • Powerful package ecosystem

  • Active community support


  • Poor memory management

  • Lacks security features

  • Quality of some packages are average


Although some languages offer better oppurtunities and use cases over the other still every language is unique and useful in its own way no language can be defined as an ultimate all rounder. It according to the requirement of the user or developer and completely depends on them as to which language to choose.
