Add PromiseValue type

[resynth1943]

Boom.

Closes #42.

[resynth1943]

@fregante How about now?

Looks better. How about we drop the asyncFunction mention though? This would let the user focus on this type and nothing else.

[resynth1943]

Do you mean the import bit?

[fregante]

I meant ReturnType, the example should not include ReturnType<typeof asyncFunction> but just PromiseValue<somePromise>

As discussed earlier, it seems that every example of PromiseValue is exactly that PromiseValue<ReturnType<typeof asyncFunction>>, suggesting that this type is useless on its own (as opposed to just having AsyncReturnType<typeof asyncFunction>).

Is it the case? Can you have an example of PromiseValue without using ReturnType? Because once #49 is added, then this example would be "obsolete"

Thanks for your comment, @fregante. I'll say thanks for your contribution, however I'd still like to see this Promise-unpacking type implemented as a separate module to the variant that unpacks the return value from functions. Moreover, I still believe this type has uses on its own.

Thank you for mentioning the asyncFunction fragment of the code though, I'll be sure to modify that to something that doesn't talk about what's basically AsyncReturnType.

Right, I’m not disagreeing, I’m just asking to show a real use in the examples as well.

Looks good 👍

[resynth1943]

Thanking you. How about we go for AsyncReturnType on top of this? ♥️

Let's do it.
