All About JavaScript in Web Development
1. What is JavaScript?
JavaScript is a powerful programming language used to add interactivity,
functionality, and dynamic behavior to web pages. It runs on the client side and
allows developers to build interactive experiences.
Often referred to as the "brain" of a webpage.
Works seamlessly with HTML and CSS.
2. Features of JavaScript
Lightweight and Fast: Executes directly in the browser without server
interaction.
Versatile: Can be used for front-end and back-end development.
Event-Driven: Handles user actions like clicks, keypresses, and form
submissions.
Supports APIs: Works with APIs to fetch and manipulate data.
3. How JavaScript Works in Web Development
JavaScript runs in the browser and manipulates the Document Object Model
(DOM) to update the content and style of a webpage dynamically.
1. Client-Side Execution:
o Example: Validating form inputs without requiring a server request.
2. Server-Side Execution (using Node.js):
o Example: Handling backend logic, managing databases.
