You Don't Know JS Yet: The Unbooks Kindle Edition

by Kyle Simpson (Author) Format: Kindle Edition

You Don’t Know JS Yet: The Unbooks is a special, draft-edition release collecting the final remaining content from the second edition of the You Don’t Know JS Yet series. It includes the complete, previously unpublished drafts of Book 3: Objects & Classes and Book 4: Types & Grammar—books that were written in full but never formally edited or released for publication.

These chapters reflect the same in-depth exploration and care you’ve come to expect from the series, just presented here in their raw, unedited, unpolished form. They’re readable, structurally complete, and technically solid—offered honestly as-is.

This release also includes two bonus chapters on the “lost” volumes that were never written: Book 5: Sync & Async and Book 6: ES.Next & Beyond. These reflective essays explain what those books were meant to be, why they were ultimately abandoned, and what insights remain worth sharing. This is a project for the completists, the curious, and anyone who still cares deeply about understanding JavaScript, not just using it.
