Client and Server Scripting Languages

 What is Scripting?

Scripting is a way to write code that automates tasks or enhances website functionality. It is mainly used in web development for both client-side (front-end) and server-side (back-end) processing.


Client-Side Scripting (Front-End) 🖥️

What is Client-Side Scripting?

Client-side scripting runs directly in the user's web browser (Chrome, Firefox, Edge) without needing a server request. It makes web pages interactive, dynamic, and responsive.

Key Features

  •  Executes in the browser (fast response time).
  •  Reduces server load.
  •  Enhances user experience (animations, form validation, dynamic updates).

Common Client-Side Scripting Languages


LanguageDescriptionUsage
JavaScript (JS)Most widely used front-end scripting language.Interactive websites, form validation, animations.
HTML (HyperText Markup Language)Defines the structure of a web page.Content layout, text, images, links.
CSS (Cascading Style Sheets)Styles the appearance of web pages.Colors, fonts, layouts.
TypeScriptA superset of JavaScript with better structure.Large-scale web applications.
AJAX (Asynchronous JavaScript and XML)Allows web pages to update without reloading.Live search, real-time updates.

Server-Side Scripting (Back-End) 


What is Server-Side Scripting?

Server-side scripting runs on the web server and processes user requests, database interactions, and business logic before sending results back to the client.

Key Features

  •  Runs on the server (secure and powerful).
  •  Handles database operations (user login, form submission).
  •  Generates dynamic content before sending it to the browser.
