Easy timeouts with Promises

Promises does not support timeouting an operation natively, so this is the simplest, most straight forward way of timeouting an operation i could think of.

Let´s have some operation that can take unspecified amout of time:

and now let´s create a timeout function, that accepts number of milliseconds after it times out and returns a promise:

Now we just need to add some logic that cancels the first promise after the second times out. You are in luck! Promises provide

that does exactly what we need. It runs all promises in parallel and settles to first promise that is resolved/rejected.

Now let´s run it:

But we can do even better! We can enhance our timeout function to accept a promise and time.

Now we can easily use it as:

That´s it. 😊 Happy coding!
