getify/You-Dont-Know-JS
A book series (2 published editions) on the JS language.
First read
Useful directional context, not a final verdict yet
getify/You-Dont-Know-JS is better read as a directional signal than a clean recommendation. Keep the snapshot conservative and validate source activity, package reality, and close alternatives before committing to it.

Validation note
GitStar can summarize public signals for getify/You-Dont-Know-JS, but the GitHub repository is still the primary place to confirm release cadence, issue activity, and maintainer intent.

Keep trust-building context reachable, but behind the first data read instead of ahead of it.
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.
