Scope of the test

Hi! Very good article!

I'm worried about the statement that Sets are faster that objects in general when that's not true at all :(

Sets are faster for some specific operations like modification and iteration while Object and Array are WAY faster for access.

So for cases where you want a lot of data easy to access but you don't want to modify it often (like a cache)

Object is way better than set.

Guess which ones are Object and Array.

Start by locating the article text containing the claim that Sets are generally faster than objects, then review the linked jsperf comparison and image. Clarify the statement to reflect the operation-specific results; done means the article no longer presents the broad claim without the needed qualification.
