Make minor grammar corrections/updates to async/promise-chaining

[jchue]

Split out and revised changes originally in #1612

[paroche]

All changes OK. I made a couple suggestions for pretty minor improvements.

[iliakan]

@paroche should we merge it in its current state?

[paroche]

Would be OK to merge as is. I had some small suggestions but they could be done later, or not at all.

When you "assign" it to me, what exactly does that mean?

[iliakan]

@paroche that means I'm unable to resolve the matter, as it's not about JavaScript, but rather about the English language, the wording and the syntax.

So I kindly ask you to take a look, request changes and merge if you deem appropriate :)

[paroche]

OK. Just seems like you've asked me to look at things before without "assigning" them to me. I guess it's the "merge if I deem appropriate" part that might be different.

Though with these more extensive changes where I agree with some, not with others, and for others might have a third (and/or forth) suggestion, I'm not sure how to proceed -- don't think I can push it piece-meal or make revisions (except after pushing it all). And may want to give the author of the PR a chance to make revisions or comments first. So then I just comment.

[iliakan]

@paroche you use create a review and "request changes" using the button in the right-upper corner, right?

Then the PR author should review and update their PR.

[jchue]

Updated

[paroche]

OK. Too bad approving it piece-meal isn't an option (or doesn't seem to be). Seems like would be easier for long series of edits in one PR.

[jchue]

Agreed.

[paroche]

That was in response to Ilya's last comment, but I'm glad you agree. Is harder to keep track this way and it can lead to a lot of redundancy in reviewing changes.
