what if i have an object with a literal key of "-0"?

hmm that's a good point, it's not only -0 but any negative index really (which are also being added support to here) - now I'm not so sure about it given that we didn't explore that idea much further during the RFC process

It seems just like using a string placeholder won’t work, because any string could be an object key - ie, it’s an implementation question, not a semantics question.

For an array, negative indexes could indeed be supported - but you’d have to traverse down to know that’s what it was.

thank you so much for the awesome help as usual @ljharb ❤️ I'm going to close this PR in order to leave this as a ref on how we could potentially handle negative indexes in the future if that discussion ever comes back again. Otherwise I'm heading in a diff direction over #3539 which is using a special symbol to identify the empty brackets syntax instead of modifying the original string which I believe is a much more solid approach. |
