What is JavaScript?
JavaScript is a text-based programming language that can be used on both the client and server sides to make web pages interactive. Whereas HTML and CSS provide structure and design to web pages, JavaScript provides interactive components that interest users. JavaScript is commonly used in everyday applications such as the Amazon search box, a news recap video embedded in The New York Times, and refreshing your Twitter feed.
By changing a static page into an interactive one, including JavaScript improves the user experience of the web page. To summarise, JavaScript provides functionality to web pages.

4 Major Uses of JavaScript
JavaScript is most often seen in web-based apps and web browsers. However, JavaScript is utilised outside of the Web in software, servers, and embedded hardware controllers. Here are some examples of simple Uses of JavaScript:-
Building web servers and developing server applications
Aside from websites and apps, developers may use JavaScript to create basic web servers and Node.js to create back-end infrastructure.
Game development
Of course, JavaScript may also be used to develop web games. These are an excellent approach for new developers to hone their JavaScript abilities.
Adding interactive behaviour to web pages
Users can interact with web pages using JavaScript. There are essentially no restrictions to what you may do using JavaScript on a web page - here are a few examples:
With the press of a button, you may show or hide more information.
When the mouse lingers over a button, it changes colour.
On the site, scroll through a picture carousel.
Zooming in and out of a picture

Creating web and mobile apps
JavaScript frameworks may be used by developers to create online and mobile apps. JavaScript frameworks are collections of JavaScript code libraries that give developers with pre-written code to utilise for routine programming functions and tasks—essentially, a framework around which to create websites or online apps.
React, React Native, Angular, and Vue are popular JavaScript front-end frameworks. Many businesses utilise Node.js, a JavaScript runtime environment based on the JavaScript V8 engine in Google Chrome. Paypal, LinkedIn, Netflix, and Uber are a few well-known examples!
Conclusion
Because of all of the aforementioned Uses of JavaScript, it is apparent that JavaScript is here to stay. JavaScript, with all of its potential in frontend and backend programming, aids in both in the development of some of the best programmes that can be utilised globally.
