Why is nobody talking about how much Proxies break Vue 3?
Private methods: Pretty simple to explain, private methods and fields straight up do not work with ES6 proxies, its a known issue https://github.com/tc39/proposal-class-fields/issues/106

JS private class fields considered harmful
The #x syntax is ugly and many people don't like it. But if you understand how JavaScript works, you'll see that private x is not possible. Some comments on the proposal suggested private #x and there were plenty of other suggestions as well, it may be interesting to read through those discussions.

All JavaScript and TypeScript features of the last 3 years explained
> - # private... not sure why they didn't just use the "private" keyword, but I don't care. I almost always use TypeScript anyways
One of the reasons was to allow private and public fields of the same name, so that subclasses are free to add own public fields without accidentally discovering private fields. There were many more considerations that went into the design: https://github.com/tc39/proposal-class-fields/blob/main/PRIV....
There was a heated debate about this and the choice of the # sigil back in 2015 at the time private fields were being designed: https://github.com/tc39/proposal-private-fields/issues/14.

Correct use of arrow functions in React
I am using ReactJS with Babel and Webpack and using ES6 as well as the proposed class fields for arrow functions. I understand that arrow functions make things more efficient by not recreating the functions each render similar to how binding in the constructor works. However, I am not 100% sure if I am using them correctly. The following is a simplified section of my code in three different files.

React component design patterns for 2022
Working with constructor and calling super() before we can set state. Although this has been solved with the introduction of class fields in JavaScript, Hooks still provide a simpler API

JS classes are not “just syntactic sugar”
I believe this was true, but it is becoming increasingly untrue as the spec gives more and more abilities and semantics to classes. Like, as you say, private fields, and more on the way.
