What is JavaScript & What Is It Used For?

JavaScript is a versatile and powerful programming language used primarily for web development. It’s an essential part of the modern web, enabling interactive and dynamic user experiences. Here’s a detailed overview:

Understanding JavaScript

  1. Scripting Language: JavaScript is a high-level, interpreted scripting language. It is used to create and control dynamic website content, such as interactive forms, animated graphics, and complex web-based games.
  2. Client-Side Language: Originally, JavaScript was primarily a client-side language, meaning it runs on the user’s web browser without the need for server-side processing. This enables interactive web applications without constantly sending data back and forth to servers.
