1. Introduction – The Power Behind Every Modern Website
Ever wondered how a webpage changes dynamically when you click a button or hover over an image? The answer lies in JavaScript, the most widely used programming language in the world.
Understanding What is JavaScript and Its Advantages helps developers build interactive, responsive, and user-friendly websites — making it a must-learn tool for anyone starting in web development.
2. Understanding JavaScript – A Quick Overview
JavaScript is a high-level, interpreted scripting language that runs directly inside web browsers. It adds life to static HTML pages and allows developers to implement complex features like sliders, animations, and interactive forms.
Whether you’re building a small business website or a large-scale application, JavaScript ensures everything runs smoothly for the end user.
3. The Evolution of JavaScript
JavaScript was introduced in 1995 by Brendan Eich during his time at Netscape. Initially known as LiveScript, it was later renamed to JavaScript and quickly became an integral part of every browser.
Since then, updates like ECMAScript (ES6) and frameworks such as React, Angular, and Node.js have turned JavaScript into a complete ecosystem that supports both front-end and back-end developments
