I'm trying to implement this rule but I have one problem.

the eslint version strip some whitespace and I'm not sure if I should do it exactly the same or not.

Example:

function test() { return       undefined; } // --> eslint fix  function test() { return; }

It's seem to me that you don't plan to add rules like https://eslint.org/docs/latest/rules/no-irregular-whitespace should i just stip the undefined keyworld nothing else or should i do it like eslint ?

Let's not worry about the whitespace.

But if you really want to give it a try, you can follow the implementation in its implementation, and you'll end up in https://github.com/sindresorhus/eslint-plugin-unicorn/blob/1deb9bb5edf27fdb2f656add11c924dfa59fdac9/rules/fix/replace-node-or-token-and-spaces-before.js
