Optimize your pull requests for reviewer-happiness

Wrote this a while ago and continues to feel relevant as I'm reviewing pull requests from newer teammates and staring at force-pushed commit trying to figure out what changed between now and when I last reviewed it

(Title in submission is the title I originally intended and submitted to freeCodeCamp. Their editor changed it to what it is now ("How to" and "keep your code reviewers happy"). I then edited it back to what I originally submitted. The editor then overrode my edit and reverted it back )
