Introduction of JavaScript
JavaScript, developed by Netscape in 1995, is a versatile and dynamic programming language that plays a crucial role in web development. Initially created to enhance the interactivity of web pages, JavaScript has evolved into a powerful language for both client-side and server-side scripting. As a client-side language, it enables developers to manipulate the Document Object Model (DOM), dynamically updating content and responding to user interactions without requiring a page reload.
One of JavaScript's key features is its event-driven nature, allowing developers to create responsive and interactive web applications. It supports various programming paradigms, including object-oriented, imperative, and functional programming. JavaScript is widely supported by modern web browsers, making it an integral part of front-end development.
Here's a simple example of JavaScript code:
In this example, the JavaScript code defines a function (`changeText`) that changes the content of an HTML element when called. The button element triggers this function when clicked, demonstrating the interactive capabilities of JavaScript in manipulating webpage content.
