You'll never use Set again...

AnabolicSet is built around the optional ability to customize item comparisons with a custom serializer. The uniqueness is guaranteed for the return value of the serializer.

This allows you to do things like:

const set1 = new AnabolicSet([{ id: 1 }, { id: 2 }, { id: 2 }], (obj) => obj.id) // <-- serializer
set1.values() // [{id: 1}, {id: 2}]

Featuring...

• custom comparing with custom serializer (similar to Java's HashSet and hashCode)
• improved functionality based upon native Set
  • union
  • intersect
  • complement
  • isSubsetOf
  • isSupersetOf
  • all native Set methods
• extensive & broad browser support
• blazing fast 💨 (up to 70% faster than native Set for certain operations)

const set1 = new AnabolicSet([1, 2, 3, 4, 5])
const set2 = new AnabolicSet([2, 4])

set1.addAll(...[5, 6])
set1.values() // [1, 2, 3, 4, 5, 6]

set2.isSubsetOf(set1) // true
set1.isSupersetOf(set2) // true

set2.add(7)
set1.union(set2) // AnabolicSet [1, 2, 3, 4, 5, 6, 7]
