This article will talk about some in-demand programming languages that will rule this year, 2021.

The most crucial prerequisite for nearly any subject, whether it is Web Development, machine learning, Data Science, or any other, 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, must carefully examine numerous important factors such as demand and popularity, career possibilities, applications, and so on before deciding on a programming language.

JavaScript

JavaScript is one of the few well-known programming languages with a strong following and demand. Facebook, Google, Microsoft, Uber, and other well-known firms in the IT sector use JavaScript. Even though 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 being utilized for both front-end and back-end development. Its interoperability with well-known frameworks such as React, Vue, Node, and others makes it more appealing to developers. Given the millions of websites that rely heavily on JavaScript currently online, as well as the language's demand and domination, it seems reasonable to predict that JavaScript will continue to reign supreme in 2021.

Python

For many years, Python has been the preferred language of virtually everyone who is just getting started in the programming world. The main reason for this is that it has a very basic 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 cutting-edge technologies including machine learning, artificial intelligence, and data science. Rich 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.

C/C++

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

Java

The object-oriented programming language implements the well-known notion of write once, run anywhere, which allows Java programs to run on other systems that support Java without requiring a recompilation. The language is frequently utilized in the creation of Android applications, as well as web, desktop, and scientific applications. Additionally, top-tier organizations such as Adobe, Amazon, Flipkart, and others use Java and provide enticing job prospects for Java engineers.

R language

Various big tech companies, such as Facebook, Google, Uber, and others, use 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 worthwhile for your future career pursuits. It is an open-source programming language with a large collection of libraries and frameworks that is extensively 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 may also be readily integrated with a variety of data processing platforms, such as Hadoop and Spark. Cross-platform compatibility, high extensibility, powerful graphical capabilities, networked computing, and other important aspects of this language make it a more popular language among developers.

Kotlin

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

C#

Microsoft created the general-purpose programming language mainly for its net framework. The language is widely used in game development, as well as the creation of Windows programs, server-side applications, and other software. C# also comes with a large library, making it a quicker and more efficient programming language. Structured language, quicker compilation, updateable & scalable, component-oriented, complete integration with .NET library, and many more are some of the amazing aspects of the language that are commonly praised by developers. The language is constantly utilized by developers in Unity game engine software, and organizations such as Intellectsoft, Capgemini, and others are also utilizing C# for their operations, implying that employment prospects for C# developers are plentiful.

PHP

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

Go

The Go programming language is used by companies such as Uber, Google, and others. Go is a Google-developed statically typed programming language with a syntax comparable to C. It comes with a slew of useful features, like garbage collection, dynamic typing, type safety, high performance and efficiency, and so on. The language is multithreaded and may be utilized in distributed systems, cloud computing, and other applications. The coolest thing about the language is that it overcomes several fundamental problems, such as sluggish compilation and execution, the lack of a large standard library, and so on.

Scala

Scala is used by several tech titans, including Netflix, Linked In, eBay, Twitter, and others, for their various platforms and businesses. Scala is strongly recommended for beginners due to its ease of learning. The language was created largely to address difficulties that developers have with another programming language, Java. It has established a solid standing among developers throughout time. Scala is a general-purpose programming language that may be used for both object-oriented and functional programming. It has several distinctive characteristics, including slow computing, string interpolation, type inference, and high scalability. Scala code may 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 extensively utilized.
