A book series (2 published editions) on the JS language.
First read
Visible and active, but adoption proof is still thinner
getify/You-Dont-Know-JS has enough public attention and recent movement to stay on the shortlist, but package usage is still partial, so the next step should be source and ecosystem validation rather than a quick yes.

Treat stars and recent movement as discovery context only until npm or PyPI usage is available.

Method note
This label appears when GitStar cannot find strong enough package telemetry to compare attention against adoption. Compare it against other Unknown repos before treating stars as a moat.

About This Page
This page provides a quick overview of getify/You-Dont-Know-JS based on GitStar's cached data. The signal chart reconstructs approximate checkpoints from current stars plus cached daily, weekly, and monthly star deltas, so it is best read as directional context rather than as a precise historical audit log.
