i have this in my codebase:

 if (
      reproject?.fromProjectToLocalSpace &&
      reproject?.fromLocalToProjectSpace &&
      reproject?.toElevation &&
      lastCorners.current &&
      pivotRef.current
    ) {
    ......

where the first three can be a function or undefined.
does that actually check if it is udefined or will it always return true (like eslint suggests me: This condition will always return true since this function is always defined. Did you mean to call it instead?ts(2774)). I know for a fact that these functions can be undefined!

does it make more sense to do something like this:

 if (
      typeof reproject?.fromProjectToLocalSpace === 'function' &&
      typeof reproject?.fromLocalToProjectSpace === 'function' &&
      typeof reproject?.toElevation === 'function' &&
      lastCorners.current &&
      pivotRef.current
    ) {

what is the right way to handle this?
