Full Stack Web Dev (2020)| XHR Sends Data to The Back-End (Junior Dev)

You've captured data from the user on the front-end. How do we send it to the back end? I start guiding you through how front-ends and back-ends communicate with GET and POST. Starting with the XHR object.

For Junior Developers just getting into web development, understanding the fundamental back and forth of both the client and server is nothing short of necessary.

The XHR object is what gets us started. XML - a scripting langauge like HTML, but with the ability to create your own tags (we don't write the object with XML; we use Javascript) HTTP - a ruleset for how clients and servers, backends and frontends, should send data back and forth Request - the object sent by your browser to the backend; this tells the backend who you are and what you're doing there

We create this object and send dummy data to a dummy site that'll respond back. This is how we'll know if we're successful in communicating with the backend.

These are the first steps in executing on the request and response nature of web development.
