JavaScript Inside Out How Your Favorite Programming Language Is Being Created?
summary
Explains how JavaScript features move from a napkin idea to shipping through a stage 0–4 process with roughly 50–60 active meeting attendees and ~150 members total, requires consensus (nobody objects), and needs runnable tests before stage 4 via Test262 (implementers run those tests). Gives concrete failures: decorators were reworked for performance, adding Array.prototype.group breaks old sites so the name changes, and the temporal stage 3 date replacement is imminent.
