Node module issues when gradually upgrading to React 17 from React 15
I've run into a weird issue when trying to gradually upgrade. If you don't know, React Gradual upgrade is a fun process where you require three package.json's - one in the root directory, one in src/legacy and one in src/modern.

TodoMVC App Written in Vanilla JavaScript
The event listeners get cleaned up by the GC. At least in modern browsers.
While events aren’t explicitly mentioned, MDN offers an insightful read:

Alternately, one can use event delegation [0]. As does React under the hood [1].

Simulate global state tradeoffs in React concurrent mode
If you aren't sure why state tearing was a hot topic a few years ago, when React's concurrent mode was first discussed, this github discussion should help: https://github.com/reactwg/react-18/discussions/69.
