How duplicates removal is implemented in Set (ES6)?

Question

I am wondering how Set in ES6 is implemented under the hood. For example, if we do new Set(arr) and there are duplicates in arr, how Set removes them?

it just does not insert them – skyboyer Jan 10 '19 at 10:25 — skyboyer, Jan 10 '19 at 10:25

It is done by checking the value equality ( === ) for every value in the set. If a duplicate value is found it isn't stored in the set.
