Build your own React
We are going to rewrite React from scratch. Step by step. Following the architecture from the real React code but without all the optimizations and non-essential features. If you’ve read any of my previous “build your own React†posts, the difference is that this post is based on React 16.8, so we can now use hooks and drop all the code related to classes. You can find the history with the old blo

We have a problem with promises
Fellow JavaScripters, it's time to admit it: we have a problem with promises. No, not with promises themselves. Promises, as defined by the A+ spec, are awesome.
