Property not assigned to child class when set by parent about tsx HOT 3 CLOSED

This is happening because of useDefineForClassFields.

TypeScript (and ts-node) sets the target to ES3 by default, which yields this behavior. But tsx sets the target based on your Node.js runtime version.

Can you make your reproduction minimal?

1 or 2 files if possible.

And remove the types, convert it to JS, and verify it works expectedly in Node.

from tsx.

Done. You now have three commands: start for JS, start-tsx, and start-ts-node, so you can compare them. Btw, I also observed this behavior with SWC, which makes me suspect it's a strict mode thing or a configuration issue.
