maybe interesting: the obj destructuring may be a bit faster than array destructuing (and not destructuring at all is sometimes a bit faster too). setup a small benchmark here https://jsbench.me/eolakmvsor/1
just storing the data and accessing it as a tuple seems to not be the significantly slow part, but instead its destructuring the array that can be a bit slow. i remember seeing some threads with e.g. useState hooks in react needing array destructuring optimizations, but appears to still be a bit slower https://docs.google.com/document/d/1hWb-lQW4NSG9yRpyyiAA_9Kt...
caveat: depends on browser (chrome vs firefox behavior is different for example) and may vary over time
