AJAX JavaScript XHR and Fetch

AJAX JavaScript XHR and Fetch

Welcome to our introductory course for using AJAX - Asynchronous JavaScript And XML

AJAX allows web pages to request small chunks of data (such as HTML, XML, JSON, or plain text) and display them only when needed.  This is achieved by using APIs like XMLHttpRequest or Fetch API. These technologies allow web pages to directly handle making HTTP requests for specific resources 

Typically when a user goes to a website the user has to wait for the server to respond with the data.  This is not the case as with AJAX we have the option to load the data when the user is already on the page making the user really happy.

This course covers making AJAX requests using the XMLHttpRequest as well as the newer fetch.   

Use JavaScript to send requests, receive response content and use the response data to output into the html.  JavaScript is at the center of it all connecting the web page content to the server data and doing all the work in between.
