Shawn Wang demonstrates how React Hooks work under the hood by building a tiny clone of React using JavaScript closures.
"Getting Closure on React Hooks" presented by Shawn "Swyx" Wang at JSConf.Asia 2019 The design of React Hooks requires a good understanding of closures in JavaScript. In this talk, we’ll reintroduce closures by building a tiny clone of React! This will serve two purposes – to demonstrate the effective use of closures, and to show how you can build a Hooks clone in just 29 lines of readable JS. Finally, we arrive at how you get Custom Hooks and the Rules of Hooks out of this incredible mental model! Originally from Singapore, swyx is an Infinite Builder working on Developer Experience at Netlify. In his free time he helps people Learn in Public at Egghead.io and /r/reactjs.
