What Is JavaScript Used For?
Javascript is a programming language that allows developers to create dynamic, interactive web applications and browsers. With 97.0% of all websites using it as a client-side programming language, JavaScript is the world's most widely used programming language. Languages that execute on the user's computer rather than a server are known as client-side languages.
JavaScript is adaptable enough for various software, hardware controllers, and server applications. Because it is built into web browsers, JavaScript is most recognized for being a language used on the web. Similar to how a native English speaker effortlessly understands English, the web browser can understand the language.
JavaScript has evolved over the past 25 years into a robust and approachable programming language for use with web browsers. JavaScript is a computer language used to build sophisticated interactive websites, browser games, and connections between servers, websites, and web applications. Given its adaptability, it is simple to understand why this language is the most widely used programming language in the world.
Web sites become dynamic thanks to JavaScript. Before JavaScript, only HTML and CSS were used to create web pages. Except for hyperlinks, HTML and CSS can only be used to style static websites that are not interactive. JavaScript is used to develop some popular websites, such as Facebook, YouTube, and Google. To develop such websites, take up a full stack web development course and learn to create websites and applications with industry experts.
JavaScript enables programmers to add features like:
The wide library of JavaScript frameworks enables programmers to create mobile and online applications quickly. Developers employ frameworks, which are collections of pre-written JavaScript code, for common functionalities. A JavaScript framework can be compared to a blueprint.
The most widely used frameworks for JavaScript applications are:
Some of the most potent social networking programs in use today are powered by Facebook's React and React Native frameworks, which the company created. Uber, Pinterest, Netflix, Instagram, Amazon, Twitter, Udemy, and many other websites use React. React Native is utilized by Facebook, Instagram, Shopify, Words with Friends, Skype, Pinterest, Discord, Tesla, and Uber Eats.
In-browser games are regularly made with JavaScript. Programmers use JavaScript to make platform games, 2D and 3D puzzles, racing games, and more. As a novice, making a small browser game might be a wonderful way to start honing your JavaScript abilities. Numerous JavaScript game engines that are open-source and free provide frameworks for making games. JawsJS, DarlingJS, and Backbone are the three most well-known gaming engines.
Brendan Eich at Netscape created JavaScript to get around the limitations of static web pages. Eich set out to develop a web-based scripting language that followed the Java programming language's grammar.
JavaScript is intended for:
JavaScript is an essential programming language for any web developer, regardless of whether you intend to focus on front-end, back-end, or full-stack development. The dynamic and interactive web pages that have evolved into the norm for user experiences that we all know, love, and depend on wouldn't exist without JavaScript.
Javascript is technically a front-end language because it is a client-side language. However, JavaScript may also be utilized in the back end thanks to the Node.js framework. It is a good idea to employ JavaScript throughout the stack, for both the front-end and the back-end, as it results in a more coherent application. The more code that is written in a single language, the easier it is to manage, update, and create with a single team.
JavaScript makes websites dynamic and interactive when utilized on the front end. It verifies submission forms, updates certain material on the page without changing the entire page, displays animations, and shows and conceals menus. The Node.js framework, when used for the back-end, enables a server to manage front-end data updates and develop scalable network applications to handle multiple user requests simultaneously. If you're a tech aspirant looking to excel at programming languages used by developers, you can enroll yourself in a full stack developer course and become job-ready.
