Top 5 Backend Development Languages To Learn In 2021

If you are a newbie in web development, the most critical part is to choose backend development languages and where to begin. Once you decide your path, you can further move forward in this field. Nowadays, there are hundreds of frontend and backend languages used in web development. Each has its own features, functionalities, complexities, and tools. 

For instance, if you choose PHP as a backend development language for you, you can easily move to advance steps, your career, and your career goals. In this article, you will learn the most popular and in-demand backend languages that are used for web development, app development, software development, and gaming. So, let’s get into it!

Top 5 Backend Development Languages

There are many popular backend languages in this era of technology. Every language has its own popularity and importance in the field of development. However, the following are some of the best languages used for development. Let’s start with the JavaScript language!


Without using JavaScript, it is impossible to make an interactive website nowadays. Javascript has become an essential part of the development of applications, websites, and software. It provides the animation facility and attractive designs of the websites. According to a Stack Overflow report, JavaScript has been the most popular programming language for developers for 8 years in a row. According to a survey, 70% of the developers used Javascript last year. You can imagine from these statistics how much JavaScript is popular in development.

Another reason for the popularity of JavaScript is that it can be used as a front-end and back-end as well. JavaScript is essential for front-end web development like HTML and CSS. JavaScript is used by the majority of the web’s most popular sites, from Facebook and Twitter to Gmail and YouTube, to create interactive web pages and dynamically display content to users.

Although JavaScript is primarily a browser-based front-end language, we can also use it on the server-side via Node.js to build scalable network applications. Node.js is supported by Linux, SunOS, Mac OS X, and Windows.

JavaScript is one of the easiest programming languages for beginners to learn because of its versatile, flexible syntax and compatibility with all major browsers.


Swift is a good place to start if you’re interested in Apple products and mobile app development. Apple developed swift in 2014. Swift is the relatively latest programming language that is used to develop iOS and macOS applications.

Swift has been performance-optimized and created from the ground up to meet the realities of modern iOS development. It not only runs iOS on every iPhone and iPad but also serves as the foundation for other operating systems such as watchOS (for Apple Watches) and tvOS (for televisions) (for Apple TVs). Furthermore, as a tech industry leader, Apple isn’t going anywhere, and iOS apps continue to be the most profitable in the mobile app marketplace.


If you are familiar with Java — a classical programming language — you should also know its modern version, Scala. Scala comprises the best features and functionalities of Java with a modern technology twist.

Scala, as a functional programming language, enables engineers to improve the quality of their code so that it replicates pure math. Scala supports concurrent programming, which enables complex procedures to be executed in parallel. It is also a strongly typed language. Engineers develop and customize their own data types, knowledge of entire swaths of bugs are impossible to detect at runtime.


Go is the little language that could, and it is one of Google’s core languages. Go, as a low-level language, is ideal for engineers who want to get into system programming. It has a lot of the same functionality as C and C++, but without the difficult syntax and sharp learning curve. It’s ideal for creating web servers, data transmission lines, and even machine-learning packages.

Go, as a compiled language, runs “close to the metal,” allowing for a lightning-fast execution time. Because it is an open-source language, ambitious developers can see their personal contributions utilized and enjoyed by programmers all over the world.


Python is possibly the most approachable programming language on this list. Python’s syntax is often described as clear, intuitive, and almost English-like, which, like Java, makes it a popular choice for beginners.

Python has a wide range of applications that make it a versatile and powerful option when deciding the best programming language. If you’re interested in back-end web development, for example, the open-source Django framework, written in Python, is popular, simple to learn, and packed with features. Django has been used in the development of a number of well-known websites, including Mozilla, Instagram, and Spotify.

Python also includes packages such as NumPy and SciPy, which are widely used in scientific computing, mathematics, and engineering. TensorFlow, PyTorch, sci-kit-learn, and OpenCV are among the Python libraries used to create programs in data science, machine learning, image processing, and computer vision. Python’s science and data applications make it an excellent choice for academics.


Although the field of computer programming is rapidly changing, the backend development languages we’ve discussed above have a lot of lasting power. By learning one or more of these languages, you will be well prepared for the next coming years.

you can only answer the question of the best programming language to learn when you are just starting out. Choose the backend development language based on your interests and the type of software development you want to follow. I hope you have understood the best backend programming languages. If you have any questions regarding this, you can contact different instructors for further information.
