let me know if you want any changes. i'm not so happy about the amount of new consts lying around, but figured it is simpler than having some set of pairs i iterate through.
also @juliangruber, would you ever consider doing patches to 2.x? many millions of the downloads are still CJS (2.x), it would be good to get this perf gain out to them since they're unlikely to move to ESM sooner
