An Async Request is a event-driven request where:
- you don't need a response from the server because you're not requesting or asking for anything
- you just want to communicate or inform that “something happened.”
This type of request is also called fire and forget.
In most cases, it's only important to have some confirmation that the request was received.
Async vs Sync
In the synchronous communication paradigm, you make a request and wait for the response (ie http protocol)
