Today, new languages are being created to build a new level of applications that have advanced features and also meet demanding needs of businesses and users.

New programming languages don’t always bring forward big changes. There are many powerful languages that always are around. Among them JavaScript that is always in the list of popular programming languages and developers and industry leads are falling in love with it all the time using it everywhere: on the web, mobile, server and even on IoT. 

But why do industry giants and a huge number of developers use it so much? What makes this language so attractive to so many? And why it is talked so much? Let’s point to the reasons. 


JavaScript is used as much as it is talked. A lot of data analysis platforms prove that it is the most popular technology in the engineering world․ Let’s start from GitHub. GitHub is one of the largest repositories that is used today by millions of developers. Yearly they publish analytics on how things went at their platform in the previous year. According to the GitHub’s Octoverse 2017, JavaScript is the most popular programming language with the number of opened pull requests. Pull requests are an indicator of the amount of code being written.

According to Stack Overflow’s Annual Survey of 2018, for the sixth year in a row, JavaScript is the most commonly used programming language. It is notable also to mention that among the most commonly used libraries, frameworks, and tools, JavaScript-based technologies like Node.js, AngularJS, React top the list. 

Now it is time to see what data we have from Redmonk. RedMonk, an industry analyst company, extracts language rankings from GitHub and Stack Overflow and combines them for a ranking that attempts to reflect both code and discussion traction. Though their ranking is not a statistically valid representation of current usage, correlating language discussion and usage, it gives insights into potential future adoption trends. And as stated in the RedMonk Programming Language Rankings of January 2018, JavaScript ranks as the first technology used and talked worldwide. 


Another really impactful reason of this technology’s high usage is its implementation by many major companies in the industry like Google, Facebook, Alibaba, Microsoft, etc. This fact undoubtedly has a big role in its popularity. The reason why these giants are using JavaScript is that it is able to handle and solve most of the tasks. It is powered by its unique nature, its libraries, and numerous highly popular frameworks that give this technology strengths everywhere.

Paypal, Yahoo, NetFlix, Slack, GoDaddy, for example, have written their web applications fully in JavaScript. Adblock Plus, HubSpot, LastPass and many other popular browser extensions run JS script under the hood. Slack, Lightshot, Mozilla, Greasemonkey are desktop apps built with this technology. Paypal, for example, migrated from Java to JavaScript and Linkedin has changed its server-side into Node.js. And Facebook always has the back of this technology supporting React and React Native technologies, constantly improving and developing them.

All these changes and treats by the industry leaders bring forward the concept of trend and influence, thus making JavaScript more attractive to other developers. As they believe that major IT companies always go for the best.


In fact, the reasons are many. JavaScript is popular because it is the king of the web and the queen of the mobile, it successfully competes with the server-side languages and doesn’t stay back even in the Internet of Things. The technology is very powerful, efficient and great for building fast and high-performing web, desktop, and mobile apps, browser extensions this is why it has great support from the industry leaders and is loved by millions of developers․ And in short, it is everywhere because it does everything in the most effective and easiest way.

So would you choose JavaScript for your next project?
