Honestly the best way to get good code at least with typescript and JavaScript is to have like 50 eslint plugins

That way it constantly yells at sonnet 4 to get the code at least in a better state.

If anyone is curious I have a massive eslint config for typescript that really gets good code out of sonnet.

But before I started doing this the code it wrote was so buggy and it was constantly trying to duplicate functions into separate files etc
