About this item

A compact, printable reference for React hooks. Each of the 15 entries has a one-line explanation and a small example you can paste into your editor. The PDF uses a two-column A4 layout designed to sit next to your keyboard, and the same content ships as Markdown so you can search it or drop it into your notes. Every React (JSX) example targets React 19.
