The most crucial requirement for almost any subject, be it web development, machine learning, data science or anything else, is the ability to program in a programming language. And year after year, we see how the rankings of these programming languages ​​change in response to developer demand and popularity. Beginners, in particular, should carefully research numerous important factors such as demand and popularity, career opportunities, applications, and so on before choosing a programming language.


JavaScript is one of the few well-known programming languages ​​with a strong following and demand. Facebook, Google, Microsoft, Uber and other well-known companies in the IT sector use JavaScript. While the language is most recognized for adding responsive components to web pages, it has a wide range of uses in web development, game development, mobile application development, and more. Furthermore, the language is used for both front-end and back-end development. Its interoperability with well-known frameworks such as React, Vue, Node and others makes it more attractive for developers. Given the millions of websites that currently rely heavily on JavaScript, as well as the demand and dominance of the language, it seems reasonable to predict that JavaScript will continue to reign supreme in 2021.


Python has been the language of choice for almost everyone just starting out in the programming world for years. The main reason for this is that it has a very simple syntax that is easy to read, understand and apply. The language is widely used in web development, software development, and other fields, as well as with numerous advanced technologies, including machine learning, artificial intelligence, and data science. Extensive library support, automated garbage collection, better interaction with other languages, GUI programming support and many other features are included in the language. Django, Flask, Pyramid and other popular Python frameworks make things more efficient and convenient.


Both C and C++ have significant presence in the IT industry and are now at the top of several indices. Many large IT companies, such as Adobe, Oracle, Microsoft, Nvidia and others, hire C/C++ professionals with competitive salaries. C is a general purpose procedural programming language mostly used in creating low level systems such as operating systems, kernel development and other applications. The features of this language are passed on to many other programming languages. C++, on the other hand, is a programming language that focuses on objects (developed primarily as an extension of C). The language is widely used in various industries, including game development, GUI and desktop applications, and competitive programming.


The object-oriented programming language implements the well-known idea of ​​write once, run everywhere, allowing Java programs to run on other systems that support Java without the need for a recompilation. The language is commonly used when creating Android applications, as well as web, desktop, and scientific applications. Moreover, top organizations such as Adobe, Amazon, Flipkart and others use Java and offer attractive job prospects for Java engineers.

R language

Several major technology companies such as Facebook, Google, Uber and others are using the R programming language for their businesses, and with the rapidly increasing demand for data science and machine learning trends, learning the R programming language is undoubtedly worth your while. future career pursuits. It is an open-source programming language with a large collection of libraries and frameworks widely used in the fields of data science, statistical analysis, and machine learning. GNU/Linux and Microsoft Windows are both well suited to the language. It also integrates easily with various data processing platforms, such as Hadoop and Spark. Cross-platform compatibility, high extensibility, powerful graphics, network computing and other important aspects of this language make it a more popular language among developers.


Kotlin is a general purpose, statically typed programming language that supports both object-oriented and functional programming capabilities. The biggest feature of the language is that it is fully compatible with Java and supports all Java libraries. In addition, the language is very easy to learn and can be used for developing online and desktop applications in addition to Android development. Some of the most popular frameworks for Kotlin are Javalin, KTor, and Vert.x, and companies like Pinterest, Uber, Netflix, and others hire Kotlin engineers.


Microsoft created the general purpose programming language mainly for its network framework. The language is widely used in game development, as well as in creating Windows programs, server-side applications, and other software. C# also comes with a large library, making it a faster and more efficient programming language. Structured language, faster compilation, updatable and scalable, component oriented, full integration with .NET library and much more are some of the amazing aspects of the language that are widely praised by developers. The language is constantly used by developers in Unity game engine software, and organizations such as Intellectsoft, Capgemini, and others also use C# for their operations, implying that the employment prospects for C# developers are abundant.


PHP is widely used by several well-known websites including Facebook, Wikipedia, WordPress and others. Website creation uses the open-source server-side scripting language, and it has features such as cross-platform compatibility, object-oriented programming capabilities, easy interaction with HTML, CSS, JavaScript, and other languages, as well as a large user community. Beginners should consider learning this language as it is very easy to master. Laravel, Symfony, CodeIgniter, and others are some of the most popular PHP frameworks to consider.

To go

The Go programming language is used by companies such as Uber, Google and others. Go is a statically typed programming language developed by Google with a syntax similar to C. It comes with a whole host of useful features such as garbage collection, dynamic typing, type safety, high performance and efficiency, and so on. The language is multithreaded and can be used in distributed systems, cloud computing and other applications. The coolest thing about the language is that it solves several fundamental problems such as slow compilation and execution, lack of a large default library, and so on.


Scala is used by several tech titans, including Netflix, Linked In, eBay, Twitter, and others, for their various platforms and businesses. Scala is highly recommended for beginners because of its ease of learning. The language was largely created to address problems developers have with another programming language, Java. It has built a solid reputation among developers over time. Scala is a general purpose programming language that can be used for both object-oriented and functional programming. It has several distinguishing features, including slow computing, string interpolation, type inference, and high scalability. Scala code can also be translated to bytecodes and run on the Java virtual machine. Web development, data science, and machine learning are all areas where the language is widely used.
