INTRODUCTION
JavaScript, often abbreviated as JS, is a high-level programming language primarily used for building dynamic and interactive web pages. It runs in web browsers, enabling developers to create features that enhance user experience.
What is JavaScript?
JavaScript is a versatile scripting language that allows developers to add interactivity, manipulate the DOM, manage asynchronous operations, and more. It was created by Brendan Eich at Netscape in 1995 and has since become an essential skill for web developers.
Importance in Web Development
In the world of web development, JavaScript is a cornerstone technology. It enables the creation of responsive and engaging web applications. Modern websites rely heavily on JavaScript to deliver dynamic content and provide users with seamless interactions.
Setting Up Your Development Environment
Before diving into JavaScript coding, you need to set up your development environment. Choose a code editor like Visual Studio Code or Sublime Text, and install Node.js for running JavaScript outside of the browser. This will allow you to practice coding and experiment with different concepts.
