Home / The Top 7 Programming Languages will Dominate the Technology world in 2021

There are several programming languages out there. Nevertheless, new ones are still emerging.  But the main question is which one runs the entire market or which programming language is the most popular and best suited for web and mobile application development.  IEEE Spectrum has released its annual list of top programming languages. The interactive rankings are created by weighting and combining various metrics from eight sources CareerBuilder, GitHub, Google, Hacker News, the IEEE, Reddit, Stack Overflow, and Twitter.

The IEEE Spectrum comes with a list of 2021 top programming languages. The list of programming languages are based on popularity.

Top Programming Languages


In the past few years, Python has been the favorite programming language of almost all individuals who have just started in the field of programming Domain. The main reason behind it is a very simple syntax that makes it easy to read, learn and use.

Python's compatibility with cutting-edge technology such as Artificial Intelligence (AI) and Machine Learning (ML) makes it more appealing to programmers.

Popular Frameworks – Django, Flask, Pyramid.

YouTube, Quora, Instagram, and Pinterest are popular apps built using Python.


Java is one of today's most common and in-demand computer programming languages.  There are approximately 8 million JAVA developers worldwide-perhaps this number can help you assess the demand and popularity of this particular language.

One way to prove that Java is good is that when Google first launched its mobile operating system, it was Google's choice to create Android applications. Java is widely used in Web and application development and big data.

Java is also used on the back end of some popular websites, including Google, AmazonTwitter, and YouTube.

Popular Frameworks – Springs, Hibernate, Struts

C & C++

Both C and C++ are occupying a considerable portion of the tech world and currently ranking at the top positions on various indexes.

Both C and C++ are considered high-performance languages. Therefore, they are widely used to develop performance-critical applications, such as client/server applications, commercial products such as Firefox, Bloomberg, Adobe, and video games.

Companies such as Nvidia, Google, Microsoft, and Apple are often looking for C/C++ developers.

Popular frameworks – MFC, .Net, Qt, KDE, GNOME.


Many languages came and disappeared, but JavaScript is one of the few well-known languages that enjoy a high reputation and demand in the programming world. JavaScript was called LiveScript when it was first shipped with Netscape Navigator 2.0 in September 1995. Later, it was renamed JavaScript.

JavaScript used for both backend and frontend programming. This is one of the most popular coding languages widely used within the Internet of Things (IoT).

Although the language is mainly used to add responsive elements on web pages, it has a wide range of applications, such as web development, game development, mobile application development, etc.

Instagram, Accenture, Airbnb, Slack are popular organizations using JavaScript.

Popular Frameworks – Node.js, Angular, React.js, Vue, Meteor

R Language
R is another emerging name in the programming world! It is open-source programming that is widely used in the fields of data science, statistical analysis, and machine learning, and provides you with a set of libraries and frameworks. The language is very suitable for GNU/Linux and Microsoft Windows.

Various large technology companies such as Facebook, Google, Uber, etc. are using the R language for their business, and considering the rapidly growing demand for data science and machine-learning trends, learning the R programming language is undoubtedly for your future a career worth it.

Popular Studio – R Studio

Go (Golang)
Go, also known as Golang, is a programming language developed by Google. Because of its simple, modern structure and familiarity with grammar, it has become popular among many large IT companies. Currently, this language is one of the most widely used languages in Silicon Valley.

It provides you with many rich functions, such as garbage collection, dynamic typing, type safety, high performance, and high efficiency, etc.

Companies that use Go as their programming language include Google, Uber, Twitch, Dropboxetc. Due to its agility and performance, Go is also becoming more and more popular among data scientists.

Popular Frameworks – Martini, Gin Gonic, Buffalo, Revel

Swift was developed by Apple in July 2010. Swift is a relatively new programming language used to develop iOS and macOS applications.

Swift requires fewer coding skills compared with other programming languages, and it can be used with IBM Swift Sandbox and IBM Bluemix. Swift is used in popular iOS apps like WordPress, Mozilla Firefox, SoundCloud, and even in the game Flappy Bird.

Popular Frameworks – Quick, Vapor, SwiftMonkey, Kitura

Bottom Line

As you can see, the future of the software development industry looks very promising. The current trend of programming languages shows that any software development project can choose a variety of top programming languages. The final choice depends on the type of application to be built and the specific business requirements.
