Top 5 Programming Languages of 2019

If you’re a software developer, then you probably—every now and then—feel overwhelmed by the super-fast pace at which our industry evolves, and that’s fine. I certainly feel that way sometimes, especially when trying to keep up with the latest trends.

But it’s possible to be well-informed about what’s going on out there, and use that information to your advantage, by being economical about your learning.

Sure, there are lots of programming languages. Sure, new ones keep being created every week—and don’t even get me started on JavaScript frameworks.

Do you need to learn all of them? Of course not.

First, learn about a number of the most popular programming languages. Then, narrow that list down, by picking the ones that make the most sense for your current knowledge level, employment status and other criteria that might make sense for your scenario.

For instance, if you intend to learn the functional paradigm, then pick a functional language from the list. Rinse and repeat.

That’s what this post is about. We’ve done the legwork for you, compiling a list of five of the most popular programming languages for 2019. Now you only have to read it and put it to good use.

A Look At Our Sources

You might be wondering where have we found our data for this post. There are hundreds of metrics to look at when considering the top programming languages, but we focused on a few of the most authoritative, namely Tiobe and GitHub.

Tiobe Programming Index

For decades, Tiobe (the software quality company) has generated an index of the most popular programming languages. They update this list monthly, pulling in data from hundreds of sources around the world.

For more on how the Tiobe Index is calculated, see here.


GitHub is one of the largest code repositories in use today. Every year they create a Year in Review report, sharing statistics about their programmer community. We use this data as another indicator of language popularity.

In this post, we also attempt to predict the future of programming languages.

We use a wide variety of resources to predict the fastest growing languages and the most influential languages. Of course, all of these insights are up for debate, but they are worth considering if you want to stay ahead of the curve.

Let’s get into it. Below are the most popular programming languages of 2019, and predictions about the future of code.
