I’m sure at some point, you’ve probably asked yourself, “What coding language should I learn?” After all, you don’t want to waste your time on a language that isn’t useful. Your choice of programming language should be relevant and in demand in today’s market. You’ll also want to pick a coding language that’s widely used and is a suitable match for your interests and your goals.

In this blog, we’ll be going over the most popular programming languages of 2021. We’ll also go over their most common use cases and how they may benefit you.

JavaScript

Consistently coming in as one of the most popular coding languages is JavaScript. Stack Overflow’s 2020 Developer Survey ranks it #1 by a good margin. JavaScript is a front-end web development language that is primarily used to manage the behavior of web pages. With JavaScript, you can code interactive buttons, animations, maps, and much more. JavaScript is often used alongside HTML and CSS for web development to give a higher level of website control.

The reason for its popularity is that JavaScript is used by the majority of the web’s most popular sites. Facebook, Twitter, Google, and many others use JavaScript to enhance and improve their user experience. JavaScript drives their interactive web pages and content.

While primarily a front-end language, JavaScript is also be used server-side through Node.js. Node.js is primarily used to build scalable network applications and is compatible with Windows, macOS, and Linux.

JavaScript is also a forgiving language to learn for beginners. It is a relatively easy language to learn, and once you begin, you can immediately practice and test your knowledge. Since it is one of the most popular coding languages, there’s an enormous amount of communities, groups, forums, and support available online. Knowledge will be easy to come by and readily available.

Another use of JavaScript is to create simple games. A list of games with source code can be found here if you want to give it a try yourself.

HTML

HTML stands for HyperText Markup Language and comes in second place on our list of most popular coding languages of 2021. As mentioned before, HTML is a front-end web development language. As it is a Markup Language, HTML is responsible for formatting the appearance of information on a website. HTML is limited to creating and structuring text on a website since its job is to describe web pages through ordinary text. Headings, links, paragraphs, and titles are all the work of HTML. A great example of an HTML text editor is WordPress.

While it is more focused on formatting than other coding languages, HTML still plays a crucial role in website functionality. It helps that HTML is also relatively easy to learn. A wide variety of resources and guides are available in forums and through videos on YouTube.

If your goal is web development, HTML is a great language to learn alongside JavaScript and CSS. All three languages complement each other well.

CSS

Cascading Style Sheets, or CSS, is usually used alongside HTML and is responsible for a website’s appearance. While HTML organizes the site’s text, CSS determines the color, position, and size of all page elements. The goal of CSS is to offer more flexibility and control over a site’s presentation and appearance. When used in conjunction with JavaScript and HTML, it can provide a smooth and intuitive user experience.

Learning CSS isn’t any more difficult compared to JavaScript or HTML. There are plenty of online learning resources, as well as a healthy community to seek advice from. As a complete kit, JavaScript, HTML, and CSS will make you a well-rounded developer.

Python

Python is one of the most popular coding languages for app development, back-end development, and has uses in video games and data science. It is a general-purpose programming language that allows software developers to use different programming styles when creating programs. Its wide range of use cases makes Python hugely popular among software developers.

With an almost clear, almost English-like syntax, Python is an easy language to learn for beginners. It comes with an extensive library that supports many common tasks and commands. Python’s use isn’t limited to only beginners, however. Thanks to its versatility, Python is used by beginners and experts alike. Companies are constantly looking for software developers with knowledge of Python, so it’s a good language to have under your belt.

SQL

SQL, or Structured Query Language, is a domain-specific language that is designed for managing data stored in an RDBMS (Relational Database Management System). In simpler terms, SQL can find and retrieve data from a database. SQL can also update existing records, remove old records, or add new records.

SQL’s main use is database management, which can be used to organize, retrieve, and store important files. Database management is a crucial requirement for businesses. That makes SQL one of the most in-demand programming languages in the market space.

If you’re looking to learn a highly marketable programming language, SQL is one of the best choices. While it is a bit harder to learn compared to other languages on this list, it has the potential to further your career opportunities.

C#

Read as C Sharp, C# is an object-oriented programming language released in 2002 by Microsoft. It is highly regarded by the community and is considered an improvement on the C++ language.

As C# is a general-purpose coding language, it has a wide range of uses in software development. You can find C# in mobile and desktop apps, cloud-based services, websites, enterprise software, and game development. The popular game engine, Unity, uses C# for all of its scripting.

Thanks to its versatility, C# is both popular and highly in-demand in the software development industry. It is also one of the easier languages to learn for beginners. C# has a huge community that actively supports new learners. You can easily find many guides, videos, and general knowledge about C# to help your learning experience.
