I think there is a typo and others is an array instead of string. A correct snippet is:

setData=(response) Excuse me, but what? I'm glad you decided to come up with this article, but please, have somebody to review it before posting it. Formatting is weird & inconsistent as well.

Hi Vebra,

Seems I missed that, I've gone ahead to update it accordingly.

@okeken, hope I didn't sound bad with my comment - just wanted to get my point across. I believe lots & lots of new developers will be reading this article of yours, which they will use as a source of truth at least to some extent, therefore it matters how well written this should be.
Other than that - mad props.
