Often referred to as ________, or Asynchronous Javascript and XML, the XMLttpRequest API lets us update part of a page in response to user actions: submit a form, request a lookup etc, all without preforming a full http request/response to reload the page.

Answer 1

The XMLHttpRequest API, often referred to as AJAX or Asynchronous JavaScript and XML, enables easy data transfer between client and server, facilitating the retrieval of data from a URL without a page refresh. This allows for dynamic updating of specific page elements in response to user actions.

Step-by-step explanation:

The XMLHttpRequest (XHR) API is a fundamental technology in web development, providing a mechanism for making asynchronous requests to a server. AJAX, short for Asynchronous JavaScript and XML, is a technique that utilizes the XMLHttpRequest API to update parts of a web page without requiring a full page reload. This is particularly valuable for enhancing user experience by allowing seamless interactions such as form submissions or dynamic content loading.

XHR enables the exchange of data between the client and server in the background, eliminating the need for the entire page to refresh. This asynchronous approach enhances the responsiveness and efficiency of web applications.
