# Foreword

> Foreword for You Don't Know JS Yet - Types & Grammar

<Note>
  This book is currently a **work in progress**. The foreword will be added as the book nears completion.
</Note>

# Foreword

The foreword for this edition will be written by a guest contributor and will be added here once the book content is finalized.

## Coming Soon

As this book continues to evolve and mature, a foreword will be commissioned from a respected member of the JavaScript community to provide context and perspective on the importance of understanding JavaScript's type system.

<Tip>
  In the meantime, feel free to jump directly to [Chapter 1: Primitive Values](/types-grammar/ch1) to begin your journey into JavaScript's type system.
