Can you show me some example of JavaScript request to the server from front-end side?

Question

Is that synonym with AJAX?

Answer 1

Here an example

Please note that front end JavaScript normally cannot fetch other domain api unless the endpoint has cors header for all sites * or specified your domain host.

Answer 2

So that means the first then() function gives the return data to the second then() ?
anyway, thanks for the example!
