AJAX (Asynchronous JavaScript and XML) is a set of web development techniques that allows web applications to send and receive data asynchronously without reloading the entire page. This enables a more dynamic and responsive user experience.

Importance of AJAX

AJAX is essential for modern web development for several reasons:

• Improved User Experience – Provides a smoother and more interactive user experience by updating parts of a web page without reloading the entire page.
• Reduced Server Load – Minimizes the amount of data sent between the client and server, reducing server load and improving performance.
• Real-Time Updates – Enables real-time updates and interactions, such as live search suggestions and chat applications.

Key Concepts of AJAX

• XMLHttpRequest – An API used to send and receive data between a web browser and a server.
• JSON – A lightweight data format often used with AJAX to exchange data between the client and server.
• Callbacks – Functions that are executed after an AJAX request is completed.

Examples of AJAX

• Live Search – Provide real-time search suggestions as users type.
• Form Submission – Submit form data without reloading the page.
