Hey Micha!
Nice post!
There is a better way to chain promises one after another. You can just return a promise within a
then
callback, like this:This way you can avoid the similarity of the "callback" hell, and you get exactly the same result in a more readable way.
First of all execute the code after 2 seconds, and then execute the code after 1 seconds.
PS: Btw, the name of the function should be
resolveAfterXMilliseconds
Hey Namir,
Thanks.
yes, this is another solution is to chain the promises. Like I have written that the given first example is just an example I have seen and should be more an anti-pattern. If you chain a lot of promises, so what you want to run your code in a sequential manner then I think that Await / Async is the even more readable solution.
Lol wanted to say the same 😉 great article btw
All of the code you've shown is running either concurrently (allowing other code to run while waiting for I/O) or sequentially (one after the other).
The term parallel refers to code that is running at the same time. If you have two pieces of code running in parallel, it means both are running simultaneously on two different CPUs or CPU cores.
You are correct.
The example maybe I chose is not the best.
I should explain it better.
It is of course not parallel on the CPU level.
For that, you need web workers.
What I meant there is that if you call for example 2 API calls they can be called in parallel. You don't need to wait for one to finish to call another one.
Thanks for making that clear! Good job!
Have a nice day!
