The best programming languages ​​for web development in 2021

Do you want to become a web developer in 2021? We have selected the best programming languages ​​you need to train in 2021!

If you want to become a web developer in 2021 but don't know which programming language to learn first, then you've come to the right place. This article introduces you to the best programming languages ​​for web development in 2021.


To put it simply, JavaScript is an object-oriented programming language. It was designed to make web development more accessible and more engaging. In most cases, JavaScript creates responsive and interactive elements for web pages, thereby improving the user experience.

In 2021, everyone agrees that JavaScript is the king of web development and possibly the most popular language among web developers. But why is it so popular? Already, it is the only language that allows you to create web applications, both frontend and backend, and mobile applications (React Native). This modern language is often used to create interactions and modify a web page on the fly. It now replaces the defunct flash, which was previously privileged to create animations.

The strength of Javascript is that it can be run on a browser and server using Nodejs and in the libraries, it has for website and application development. Javascript thus offers an infinite number of possibilities in the layout of web content.

For example, it is possible to use React.js and Angular for the frontend, Nodejs for the backend, and React Native to build cross-platform mobile apps (Android and iOS).

If you are starting a career in web development, you should learn JavaScript in 2021.

⚠️ Be careful; we often confuse Java and JavaScript, but they are not the same thing. They have in common that they are two C-type programming languages, so they have a similar code structure.

However, their use is entirely different. JavaScript is an interpreted web language that is primarily used through your internet browser. Conversely, Java is a language dedicated to Back and stand-alone applications. It is, therefore, mainly used to design software or applications and mobile.


Python is another language that has gained a lot of popularity in recent years. While it's not exactly new and has stood the test of time, it's probably the most versatile programming language around.

You can use Python for web development, data science, scripting, and automation. Like JavaScript, Python also enjoys enormous community support and has many valuable frameworks, libraries, and tools that can help you build a web application in a hurry.

The programming language includes thousands of third-party modules available in the Python Package Index (PyPI). PyPI provides popular standards for different areas of expertise, such as Django for web development and NumPy, Pandas, and Mathplotlib for data science.

Django is typically used to build complete web applications. However, you can also use the open-source Flask microframework to control your code and a minimalistic web development framework.

Python is also an excellent programming language for learning to code. If you're new to software development, turning to Python can be a great start. The advantage (and not the least) is that you can use it for web development and computer programming.


TypeScript is a modern programming language for web development. Like C and C ++, TypeScript can be thought of as JavaScript ++. Note, however, that it is not as popular as its C ++ cousin.

The advantage of TypeScript is that it adds type security to JavaScript code. In addition, it means that it makes it easier to identify JavaScript type errors in a development phase. Your source code thus (almost) always has the correct syntax.

Another significant advantage is that it facilitates the development of object-oriented code for JavaScript. For this reason, there are several debugging tools built into TypeScript that make web development easier.

If you need to choose a modern programming language to learn in 2021, learning TypeScript is highly recommended!


PHP (an acronym for Personal Home Page) is currently known as Hypertext Preprocessor. It is a server-side scripting language used for the development of static and dynamic websites. PHP can also develop web applications.

Even if developers are highly criticized (mainly for security), PHP remains one of the best programming languages ​​for web development in 2021. Indeed, PHP is essential because it is the web development language that built the most used CMS globally (WordPress, Joomla, Drupal, Prestashop, Magento…). It is, therefore, the most widely used programming language to create web applications.

To define it, we can say that it is a dynamic scripting language on the server side, making it very easy to create fully functional web applications. If you still have doubts about its usefulness, note that half of the internet works on PHP! Remember that WordPress, the most popular web application software, is built on PHP.

PHP also has elegant syntax frameworks such as Laravel. This GitHub site repository is robust and allows you to quickly create web applications using a three-level MVC architectural model (model-view-controller).

Finally, if you aspire to become a good PHP developer, you must also know SQL. PHP is used to create a program, SQL is used to interact with datasets, and most programs require some form of data to act. When developing a PHP application, you will need to create a connection to a database and then insert, delete, and select data. SQL provides a structured language for querying the database.

Don't listen to developers who say PHP is not valid. If you want to learn PHP for web development in 2021, you will find plenty of free resources on the web to train yourself.


Ruby is another programming language that is well suited for web development. Like Python and PHP, Ruby is suitable for beginners because it is easy to learn.

Ruby is a very intuitive programming language with its code syntax. This makes learning Ruby less difficult than learning some other programming languages. Ruby is also a great general-purpose language. It can be used to write scripts in the same way as Perl and create complete, stand-alone GUI-based applications. But Ruby's usefulness doesn't end there. Ruby is also excellent at serving web pages, generating dynamic web page content, and excelling at database access tasks.

Ruby's great interest in web development is the Ruby on Rails framework (also called RoR or Rails). This free web framework written in Ruby is the basis for renowned websites like Github, Shopify, Airbnb, Groupon, GoodReads, and Kickstarter.

Rails is also a model-view-controller (MVC) framework. It provides default structures for a database, web service, and web pages. In addition, it encourages and facilitates web standards such as JSON or XML for data transfer and HTML, CSS, and JavaScript for the user interface.


While HTML and CSS are not programming languages (some of you might disagree, but yes, they are not programming languages), they are the backbone of development. Therefore, the web and every web developer should learn them.

The main difference between HTML and CSS is that HTML is a markup language used to create the structure of a web page, while CSS is a styling language used to make web pages more presentable.

In short, HTML provides the structure while CSS provides the styling and improves the visual appearance of the pages. Note that for modern website design in 2021, you need to know HTML5 and CSS3, the most current versions of these two languages.

HTML and CSS are the basis of the web, and if you've never touched a codebase, this is not where you should start. The good news is that compared to other languages, they are pretty easy to learn. With the proper training, you can master them in a matter of weeks. However, if you want to become a frontend developer, you need to master these two languages ​​in 2021.


It is possible to learn self-taught, but good training will help you structure your work and retain the correct syntax and methodology to work in a team (project manager, frontend + backend developer team, etc.). Furthermore, suppose you have a perfect mastery of one of these programming languages.

In that case, you will easily find a job as a salaried web developer in a company or freelance client missions. Indeed, there is a shortage of employment, so the law of supply and demand favors developers. So don't hesitate to negotiate your salary if you are a good developer!

That's all about the best programming languages ​​for WEb development in 2021. As you may have seen, JavaScript is the king of web development! However, Python is just as good. As for PHP and Ruby, these are the easiest languages ​​for building web applications. Finally, TypoScript is a new, modern and promising programming language that you can also learn for website and app creation or redesign projects.

Finally, if you aspire to become a full-stack web developer, you must know all of these languages. This is a great goal to achieve!
