Consider the following example:
let set = new Set()
set.add([3, 6])
If I attempt to use set.has([3, 6]) I expect to receive a true but I got a false, why?

The same reason that `[3, 6] == [3, 6]` returns false. – Barmar Oct 22 '20 at 15:51

Why?, I genuinely want to know, and how can I avoid it in this case? – sandmor Oct 22 '20 at 15:52

Arrays are not compared by contents. They're compared as objects, they're only equal if they're the same object. – Barmar Oct 22 '20 at 16:02

`Set.has` uses an equality check to compare items. – Heretic Monkey Oct 22 '20 at 16:04

Does this answer your question? [Storing arrays in ES6 Set and accessing them by value](https://stackoverflow.com/questions/29760644/storing-arrays-in-es6-set-and-accessing-them-by-value) – Thales Kenne Oct 22 '20 at 16:08

So, as alternative I can store an object?, coming from low-level languages iterate an array lineary looks pretty inefficient – sandmor Oct 22 '20 at 16:33
