Coding has become one of the most sought after core skills in the job market. To introduce you to code there are multiple online courses and free workshops, such as the ones we offer at CodeClan: https://codeclan.com/events/ Computer programming is important today because so much of our world is automated and digital. Humans need to be able to control the interaction between people and machines. Code makes the Internet, mobile applications and any software you use on your devices possible. And to do all this you need programming languages, so which programming languages are the most widely used?
Since there are maaaaaaany programming languages, in this blog we’ll explore only a few of the most in-demand. If you want to get started in programming, or find a job learning to program, you should start with the most widely used and most demanded programming languages.
HTML
While not strictly a programming language, Hypertext Markup Language (HTML) is the language that makes the Web as we know it possible. So, if you are reading this on your computer, tablet or phone, it’s thanks to HTML.
Created in the early 90s by Tim Berners-Lee, it’s a language that’s fundamental to the Internet. It’s so popular that practically any web browser or text editor allows you to open HTML documents. This language allows us to create and view the basic static content on the Internet, with hyperlinks that facilitate the organisation of texts, images, headers and so on.
Jobs that require HTML: software developer, web and multimedia developer, frontend and full stack developer, UX designer, marketers, etc.

CSS
And if we are talking about HTML as a pillar of the Web on the Internet, we have to mention CSS. CSS is the acronym for Cascading Style Sheets, it complements the HTML language by adding style to web pages. With a CSS style sheet we can change the appearance and functioning of a web page, adding colour, layout, alignment, formatting, fonts and more.
Jobs that require CSS: software developer, frontend and full stack developer, web and multimedia developer, marketers, UX designers, etc. Basically, the same profiles that use HTML in their day-to-day work.

JavaScript
JavaScript is one of the most popular programming languages. Commonly used on the Web, it was created in the second half of the 90s. It was born in the facilities of Netscape, one of the first web browsers on the market. It has features of C and Java, and is used in all kinds of developments. Beyond the Web, JavaScript can be found in databases, applications, operating systems, etc.
Its use is closely linked to HTML, as it allows enriching and improving the content of web pages by offering more features and versatility. All this thanks to the fact that all current web browsers have an integrated JavaScript interpreter or engine.
Jobs that require JavaScript: software developer, frontend and full stack developer, web and multimedia developer, etc.

Python
Mobile and desktop applications, websites, online tools… JavaScript, HTML and CSS are used for this and much more. But Python has earned its spot as one of the most popular languages for its use in data analysis, being the most widely used programming language for managing, interpreting and translating data.
Python appeared in 1991 with the aim of being an object-oriented, interpreted, dynamic and multi platform language.
Many people recommend Python as the first language to get started in programming because of its features and simplicity of code. That’s why at CodeClan, for example, it’s the first programming language our software development students learn with us.
In recent years, Python’s popularity has massively increased because of its wide use in any field that requires data processing.
Jobs that require Python: system administrators, data engineers, data scientists, data analysts, business analysts, software engineers, economists.

R
R is a programming language and environment with a focus on statistical analysis.
R was born as a free software reimplementation of the S language, with added support for static scope. It’s one of the most widely used programming languages in scientific research and is also very popular in the fields of machine learning, data mining, biomedical research, bioinformatics and financial mathematics.
Jobs that require R programming: Data analysts, business analysts, business intelligence experts, data visualisation experts, quantitative analysts…
