chatgpt is suggesting like this. wdyt?

// ensure we end up with a string, whether name is an object or a primitive
const processedName = typeof name === 'object'
  ? name.name ?? ''
  : name ?? '';

// use exec if you only need the first match (avoids oddities with global regexes)
const match = nameRegExp.exec(processedName);

This would have the same issue of not handling nulls properly. typeof name === 'object' is true, so when it lands in the first branch of the ternary, name.name errors like it does now. Alternatively, if the project doesn't need to support older runtimes and/or TS downlevels enough, we can do just name?.name

ah, looks like we cannot reuse the variable name here.

don't know why I am vibe coding. how about this one?

// normalize to a string, safely handling null/undefined and objects
const safeName = String(name?.name ?? name ?? '');

// if you only need the first match, exec is a bit more predictable than match
const match = nameRegExp.exec(safeName);

Done. I skipped the String() conversion because the chain should handle nullish values and fall back to '' if needed
