Why JavaScript?
JavaScript is a versatile programming language used across the globe to create dynamic websites and applications. It’s known for its flexibility, allowing developers to bring web pages to life with animations, interactivity, and real-time content updates.
The Role of JavaScript in Web Development
JavaScript plays a pivotal role in both client-side (front-end) and server-side (back-end) development. Paired with HTML and CSS, JavaScript creates interactive user interfaces and can handle server-side logic using platforms like Node.js.
