Ajax and jQuery Basics

Ajax and jQuery are commonly used to create dynamic and interactive web applications. They’re both powerful tools that can improve the user experience and make web pages more responsive.

Ajax

Ajax is an abbreviation of Asynchronous JavaScript and XML. This is a method for developing quick and dynamic websites. Ajax enables asynchronous web page updates by exchanging tiny quantities of data with the server behind the scenes. This implies that the web page can be updated without reloading the full page. Ajax is commonly used for form validation, dynamic content loading, and shopping cart updates.

An example of how Ajax can be used is in a search feature on a website. When a user types a query into the search field, an AJAX request is sent to the server to search the database for matching results. The server then sends back the search results, which are dynamically added to the web page, allowing the user to see the results without having to refresh the page.
