Asynchronous JavaScript has never been easy. For a while, we used callbacks. Then, we used promises. And now, we have asynchronous functions.
Asy...
For further actions, you may consider blocking this person and/or reporting abuse
Not completely, as there is one case when it can be beneficial to use
return await. Let's say you have three async functions, A,B and C, where A calls B, and B calls C.Function B calls function C in a try-catch block. If B just returns the promise returned by function C than B puts the burden of error handling on function A as it's catch block will never be called. However if it uses
return await C()and C rejects the promise, the erro will be handled by function B's catch block.I might be making this waaay more complicated than it really is so here is Jake Archibald doing it much better than I did :)

Way too complicated lol. I just do this:
—-
async function test () {
await a
await b
Return c
}
Test().catch(handleError)
If C errors out, I still catch it with handleError.
