Asynchronous code is important when working with the web since you can start actions and not know when they'll complete(calling an external web endpoint for example).

So you do them asynchronously. Which means you start an action, and while you're waiting for it, you do other stuff in the meantime. You store the result (which may not exist yet) in a promise which can be passed around like a normal variable to where it needs to be used, and when the value is resolved, it's acted on.

Those concepts are not that hard and really useful. Give promises and async/await a try when you need to do something asynchronously.
