What is Javascript?

JavaScript is a high-level, interpreted programming language that is used to make web pages interactive. It can update and change both HTML and CSS, and can calculate, manipulate, and validate data.

Key Features of JavaScript:

• Client-side Language: JavaScript runs on the client side of a web application, meaning it is executed on the user’s browser.
• Event-Driven: JavaScript allows developers to define how the scripts should be executed when certain events occur on the webpage.
• Lightweight and Flexible: JavaScript is lightweight and versatile, making it easy to integrate with HTML and CSS.

How Does JavaScript Work?

JavaScript is a powerful scripting language that can be embedded directly into HTML web pages. When a web page is loaded, the browser’s JavaScript engine reads and executes the JavaScript code to manipulate the content of the page dynamically.

Key Points:

• Interactivity: JavaScript allows for interactive elements on a webpage, such as form validation, animations, and dynamic content updates.
• Client-Side Processing: JavaScript is primarily a client-side scripting language, meaning it runs on the user’s browser rather than on the server.
• Event-Driven: JavaScript responds to user actions or events, such as clicking a button or hovering over an element, to trigger specific actions.
