Introduction to JavaScript

JavaScript is a popular programming language used for creating interactive and dynamic websites. It is often referred to as the “language of the web” as it is essential for building modern web applications.

Getting Started with JavaScript

To start coding in JavaScript, all you need is a text editor and a web browser. You can write JavaScript code directly in an HTML file using the <script> tag or in a separate JavaScript file linked to an HTML file using the <script src="filename.js"> tag.

JavaScript is a versatile language with simple yet powerful syntax. Here are some basic concepts to get you started:

  • Variables: Used to store data values.
  • Data Types: Includes numbers, strings, booleans, arrays, and objects.
  • Operators: Used for arithmetic, assignment, comparison, and logical operations.

  • Changing the content of a webpage.
  • Adding or removing HTML elements.
  • Handling user input through forms.
