If you’re wondering what an API is, check out my notes on APIs
Fetch API is a tool which provides a JavaScript interface called a Request for fetching resources across the internet.
Request is an interface which tells you which resource is being requested from whom in the internet.
We use fetch() to make a HTTP request to a browser and to fetch resources from that browsers. In this method, we pass a Request object or the URL from which we need to fetch resources from.
It returns something called a Promise, which I cover in detail here.
This Promise is then fulfilled with a Response object, which represents a server’s response to what happened just now.
