Most In-Demand Programming Languages

Most In-Demand Programming Languages – You don’t want to waste your time. If you’re going to put aside the time and energy needed to learn new programming languages, you want to make sure, without a doubt, that the ones you choose are the most in-demand programming languages on the market.

After all, if you’re trying to start (or advance) a career in software development, you’ll need to be at the front of the metaphorical class. You’ll need to know which programming languages are popular, which are useful and which are up-and-coming on the market — and then set yourself up to learn them.

Not sure where to start? Don’t worry; we’ve already done the heavy lifting for you, and looked through developer and market data from the past several years to identify trends and draw conclusions that will help you plan for your programming education. In this article, we’ll walk you through the 11 most in-demand programming languages and give you a few pointers on how to learn them.

You can probably guess the rationale behind our first question. While following trends isn’t always the best way to figure out which languages to prioritize, a language’s popularity can indicate its prominence in the market. Here’s a general rule of thumb for you — the more used or common a language is, the more likely it is that a developer (i.e., you!) will need to deal with it at work.

Most In-Demand Programming Languages


According to Stack Overflow’s 2020 Developer Survey, JavaScript currently stands as the most commonly-used language in the world (69.7%), followed by HTML/CSS (62.4%), SQL (56.9%), Python (41.6%) and Java (38.4%). It is also the most sought-out programming language by hiring managers in the Americas (PDF, 2.4 MB).

JavaScript is used to manage the behavior of web pages. With it, coders can create dynamic web elements such as animated graphics, interactive maps, clickable buttons and more. Programmers who use HTML, CSS and JavaScript in tandem obtain a higher level of website control and can provide a better user experience in terms of navigation and readability.

JavaScript is the most common coding language in use today around the world. This is for a good reason: most web browsers utilize it and it’s one of the easiest languages to learn. JavaScript requires almost no prior coding knowledge — once you start learning, you can practice and play with it immediately.


Python is a general-purpose programming language that empowers developers to use several different programming styles (i.e., functional, object-oriented, reflective, etc.) when creating programs. Several popular digital tools and platforms were developed with Python, including YouTube, Google Search and iRobot machines. It is also, according to HackerRank, the second-most in-demand programming language for hiring managers in the Americas after Python (PDF, 2.4 MB).

As one of the more easy-to-learn and -use languages, Python is ideal for beginners and experienced coders alike. The language comes with an extensive library that supports common commands and tasks. Its interactive qualities allow programmers to test code as they go, reducing the amount of time wasted on creating and testing long sections of code.

That said, even advanced users would benefit from adding Python to their mental catalog of programming languages; with over 50% of hiring managers (PDF, 2.4MB) seeking candidates who know the language, Python is easily one of the most marketable and in-demand programming languages.


HTML stands for HyperText Markup Language. Don’t let the complicated-sounding name fool you, though; HTML is one of the most accessible stepping stones into the world of programming.

Technically, HTML is a markup language, which means that it is responsible for formatting the appearance of information on a website. Essentially, HTML is used to describe web pages with ordinary text. It doesn’t have the same functionality as other programming languages in this list and is limited to creating and structuring text on a site. Sections, headings, links and paragraphs are all part of the HTML domain.

As of 2020, HTML shares its #2 spot on Stack Overflow’s list of the most commonly used languages in the world with CSS.
