Top 21 Programming Languages in the World (and where to learn them)

Without a doubt, programming is one of the most lucrative careers in the world today. However, there are hundreds of programming languages and not all are equal.

It doesn’t matter if you are new to programming or are a seasoned developer, knowing which programming languages are the most popular and WHY will give you an edge and help you decide which language(s) to learn.

The problem with most programming language ranking information

A number of websites list what they believe are the most popular programing languages. But most don’t mention how they rank them. So, why should you believe them? (Maybe you shouldn’t!)

Some sites base their rankings on the TIOBE index, which measures number of search engine results (“hits”) for a programming language, or PYPL which measures number of Google searches for programming language tutorials.

The problem with these two approaches is they only tell us how often people write about or search for programming languages on the web. And it doesn’t tell us anything about how often programming languages are actually used!

How do we define programming language popularity?

To determine how popular a programming language is there are a few dimensions you could consider. Such as, what are…

With so many ways to measure popularity how do we choose?

Look at the usage numbers!

I prefer to look at how people are using code. Meaning, the amount of code written and also who is asking and answering questions about that code.

So, to rank which programming languages are the most popular we’ll take into account the number of GitHub projects (amount of code written) featuring the language vs the number of Stack Overflow tags (questions being asked and answered) for the language.

In other words, we’re defining popularity as: the amount of code written on GitHub vs number of questions asked on Stack Overflow.

Here is a chart visualizing those two dimensions (from July 2020):

Top 21 Programming Languages in the World

I want to mention:

  • The above method is not new, it was first published in 2010 and continues today at RedMonk.
  • GitHub statistics I believe are sampled from code written into public repos so this likely does not cover code written into private repos (e.g. companies). However open source code is used by companies and is some of the best data we have to measure who is writing in which coding language.
  • Also, Stack Overflow’s question/answer tags likely include people inside and outside of the open source world asking questions (includes private companies). Also a good source of data!
  • Ben Frederickson took a very cool approach and has counted how many people on GitHub use each language. Only issue with that is the data is a few years old now and doesn’t also consider the questions people ask found on Stack Overflow. But worth examining more maybe in the future.

And the most popular programming languages are…

Based on the above criteria and ordered by popularity, the top programming languages in the world today include:

  1. JavaScript
  2. Python
  3. Java
  4. PHP
  5. C++
  6. C#
  7. Ruby
  8. CSS
  9. Typescript
  10. C
  11. Swift
  12. Objective-C
  13. R
  14. Scala
  15. Go
  16. Shell
  17. PowerShell
  18. Perl
  19. Kotlin
  20. Rust

And those are just the top 20 based on the above visualization (data).

Absent from this list is HTML, which is a “markup” language and not considered a true programming language. But since there are hundreds of millions of web sites on the internet and they all use HTML, this tells me it’s pretty popular and I will add it to the list 

Here, we will take a look at each of these languages and why they are popular and worth learning today. We also recommend the best course to learn each programming language.

Programming Language #1: JavaScript

Top 21 Programming Languages in the World (and where to learn them)

Average annual developer salary: $111,000

Number of developer jobs: 43,000

JavaScript, created in 1995 (and still going strong) takes the spot for the most popular programming language.

But why?

Most websites (there are hundreds of millions) use JavaScript and is widely considered the go-to language for creating interactive web pages.

Its syntax is easy to use, making it easy for beginners to learn.

The most popular internet services in the world such as Facebook and Google are built using web web tools (e.g. “front-end” frameworks like ReactAngular and Vue) all powered by JavaScript allowing developers to create modern, interactive web applications.

It’s worth noting, in 2009 something BIG happened: enter Node.js – a way to run JavaSrcipt as a server-side language! Today, many companies use JavaScript as both a front-end and back-end language to power their software.

And did you know, you can build desktop or mobile apps using JavaScript? Yes!

Wow, JavaScript really is everywhere and without a doubt is one of the most commonly used and in-demand programming languages in the world today.


  • One of the most in-demand languages.
  • Has a flexible, beginner-friendly syntax.
  • Runs in the browser and on servers – means companies can have the same people work in both areas.
  • Extensive resources and community support (over 12 million developers).
  • Versatile and useful for building a wide range of applications, including desktop and mobile apps.


  • Can be disabled by browsers to curb malicious threats.
  • Depending on the browser (e.g. older browsers like Internet Explorer), the behavior of JavaScript may change.
  • Weakly typed – this means data can unintentionally change from one form to another (sort of like “sloppy” programming) and may lead to more bugs. However TypeScript (a superset of JavaScript) aims to fix this.

Where it’s used: JavaScript is used to add interactive features on websites, however more and more startups and tech companies are favoring JavaScript for backend use due to its simplicity and speed. And for desktop app development.

Hands down, Python is the most popular programming language of all time. Despite being an older language (first release in 1991), it has maintained an upward trajectory for many years and is has gained big popularity in recent years.

So why is Python so popular?

Well, for starters states:

Python is a programming language that lets you work quickly
and integrate systems more effectively.

“Work quickly” means the language syntax is very simple to read/write and understand. And this makes Python one of the most popular languages to learn for beginners.

“Integrate systems more effectively” means not everything you do always happens in Python. Instead Python is really good at acting as the “glue” to bring together other applications/systems.

Also to note, Python has been gaining a lot of popularity because of the rise of artificial intelligence and machine learning. Again Python is easy to use relative to other coding languages and has led to a number of libraries created specifically for for AI and ML.

Last but certainly not least, it’s one of the programming languages with the highest salary 


  • Considered a universal programming language suited to a wide array of applications
  • Clean and intuitive code makes it very easy to learn
