Ajax

Ajax (Asynchronous JavaScript and XML) is a set of web development techniques combining JavaScript and XMLHttpRequest to enable web pages to communicate with a server asynchronously. This allows for the loading of new data without requiring a full page refresh, enhancing user experience by making web applications more interactive and responsive. With Ajax, developers can send and receive data from a server in the background, updating the user interface in real time based on this data. Though originally designed to work with XML, Ajax commonly supports various formats such as JSON, HTML, and plain text. This capability is widely used in modern web applications, enabling functionalities like live searches, form submissions, and dynamic content updates.
