You'll never use [`Set`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/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:
```javascript
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`](https://docs.oracle.com/javase/7/docs/api/java/util/HashSet.html) and `hashCode`)
- improved functionality based upon native [`Set`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set)
- [`union`](https://github.com/ColonelParrot/AnabolicSet/wiki#--unionset)
- [`intersect`](https://github.com/ColonelParrot/AnabolicSet/wiki#--intersectset)
- [`complement`](https://github.com/ColonelParrot/AnabolicSet/wiki#--complementset)
- [`isSubsetOf`](https://github.com/ColonelParrot/AnabolicSet/wiki#--issubsetofset)
- [`isSupersetOf`](https://github.com/ColonelParrot/AnabolicSet/wiki#--issupersetofset)
- all native [`Set` methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Set#instance_methods)
- extensive & broad browser support
- blazing fast 💨 ([up to **70%** faster than native Set](https://jsbench.me/zrlebmbyq1/1) for certain operations)
```javascript
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]
```
