It is an interface that someone else has written the function to call for you.

API is an interface provided to different languages, that is, the corresponding method is provided in the corresponding function. All we have to do is use the syntax of js to call the desired function. For example, BOM in js has a screen method, which is the interface provided to us by the browser and can operate on the browser.
