Types of scripting

There are two types of scripting:

Client-side scripting (browser scripting)
Server-Side Scripting

1. Client-side scripting (Browser Scripting)

Client-side scripting refers to the scripts that run on the user's web browser. and JavaScript is the most common language for scripting. It is mostly supported by all browsers, and it allows dynamic scripting. It can handle user interactions like button clicks, hovers, and form submissions, and it can also reduce the load on the server as processing happens on the client side. By using client-side scripting, you can also validate the form field, access the DOM, and manipulate it to dynamically change its content.

2. Server-side scripting

Server-side scripting refers to scripts that run on the web server. and languages such as PHP, Python, Java, and Node. JS is used for server-side scripting. In server-side scripting, the script is executed before it is sent to the browser. It can handle tasks that require a database, file system, and any other server resources securely. It creates dynamic content based on user requests. You can also create an API by using server-side scripting.

Features of Browser Scripting

Event Handling allows you to respond to events like button clicks, form submitting, etc..
By using Asynchronous JavaScript XM (AJAX) you can dynamically change the content without reloading the page.
