What Development Language Should I Learn in 2020?

If you’re asking “What development language should I learn in 2020?”, then this post is for you! I too was intrigued by this question and it got me wondering how I should go about figuring this out.

It dawned on my that the best way to figure this out, would be looking at what dev jobs are being asked for – not just locally, but internationally too.

My thinking is that job postings by language and country will surely give an indication as to what employers are looking for and what skills are in demand. And here are the results:

Top 3

Here are the top 3 languages you should strongly consider learning in 2020: (no shortage of jobs with these skills)

  • Java
  • Python
  • React

(Note: C# came in 4th place)

Bottom 3

However, based on my findings, the 3 languages/skills with little to no jobs on offer:

  • Cordova
  • Haskell
  • Rust

(in other words, give these a skip)

A closer look

Below you’ll find a city in a country with dev languages ordered by the amount of jobs. To gather this info, I used LinkedIn Jobs to search for keywords, left with the default option of “within 25km” of the city.

Just a note: The cities and dev languages I’ve selected are based on my own interests, but to be broad, I’ve included some languages and cities that don’t necessarily appeal to me, but may provide insights to others.

I apologize if a dev language/city you were looking for isn’t listed below.

It should also be noted that these results are based on just one job website (of many) and some countries / cities may not use LinkedIn Jobs to it’s fullest potential.
