Fetch Data Asynchronously
This course covers everything a developer needs to know to asynchronously send and receive data in their web applications. You'll dive into how asynchronous requests work by using the XHR object to create and send asynchronous requests for image and news article data. Then, you'll see how you can perform async requests more easily using third-party libraries and APIs like jQuery's Ajax and the Fetch API.

Retrieving data asynchronously is now the norm with apps like Twitter, Facebook, and Google sending and retrieving mountains of data without having to stop and wait for processes to finish or to reload the page. Create smooth, modern web applications by using Ajax techniques to retrieve data asynchronously.
