Enhancements to the proposal Set methods #45

Open unadlib opened 3 months ago

unadlib commented 3 months ago

This is a proposal https://github.com/tc39/proposal-set-methods to add methods like union and intersection to JavaScript's built-in Set class.

It is currently at stage 4: it has been https://github.com/tc39/ecma262/pull/3306. This repository is no longer active.

This would add the following methods:

Set.prototype.intersection(other)
Set.prototype.union(other)
Set.prototype.difference(other)
Set.prototype.symmetricDifference(other)
Set.prototype.isSubsetOf(other)
Set.prototype.isSupersetOf(other)
Set.prototype.isDisjointFrom(other)

With the support of the latest major browsers, it is necessary for Mutative to support it as well.
