What is JavaScript?

JavaScript is a programming language that is commonly used to add interactive features to websites. It is a client-side language, which means that it is executed by the user's web browser rather than on a server. This allows for the creation of dynamic and responsive web pages that can interact with users in real-time.

Key Features of JavaScript

Interactivity: JavaScript allows you to create interactive web pages.

Client-Side Validation: Reduces server load by validating user input before sending it to the server.

Dynamic Content: Modify content on the webpage without reloading the entire page.

Event Handling: Respond to user actions like clicks, mouse movements, and keypresses.

Cross-Platform: Runs on any device with a web browser.

Where to write JavaScript

JavaScript

You can write JavaScript directly in an HTML file within <script> tags.

<!DOCTYPE html>
<html>
<head>
  <title>My Website</title>
</head>
<body>
  <script>
    // Your JavaScript code here
  </script>
</body>
</html>
 

You can also create a separate .js file and link it to your HTML file.

    • index.html
    • style.css
    • app.js
  • <!DOCTYPE html>
    <html>
    <head>
      <title>My Website</title>
    </head>
    <body>
    //linking js file to HTML file
      <script src='app.js'></script>
    </body>
    </html>
