We can use AJAX in JavaScript in two ways: using the XMLHttpRequest object and Fetch API. Fetch is a modern concept equivalent to XMLHttpRequest. It offers a lot of the same functionality as XMLHttpRequest, but is designed to be more extensible and efficient (MDN docs). In this article, I will introduce how to send and receive data from a server by using the XMLHttpRequest object and Fetch API through examples. I will also introduce errors that we may find and how to fix them.
Sending and Retrieving Data
The two most common methods for communicating between a client and server are GET and POST. https://goo.gl/NBQ2DZ #DataIntegration #ML
