Add helpers jsdoc (WIP)

still a work in progress, but so far... would appreciate any tips if something looks off, otherwise i'll keep on truckin'
i actually wouldn't at all be opposed to turning this into option #2 if you have no disagreements since we're at a clean slate now. it would be a long-term investment since we're on doc 2 of x.

i can stil stick to #1 though if you'd prefer that for the short-term and upgrade it later. with that being said, should i simply remove the `examples` altogether and just put the snippets in the actual function fields?
