Im copy pasting my own answer from another qs:

Go to this website, to see what an API looks like

This is an API, you can fetch data from here and use it in your applications instead of making your own data.

You can create your own APIs using technologies such as NodeJS, Express, etc, and make requests to these APIs using Javascript.

Hopefully, u'll understand it

Answer 2

You can google it.
