JavaScript Set() as it should be.
ECMAScript 6 sets have no methods for computing the union (∪), intersection (∩) or difference (⊖). Zet is an extension of ES6 Set and comes with all its functionality included. The API is similar to how sets work in Python.
Additions to the default ECMAScript 6 set
- ∪ union
- ∩ intersection
- - difference/subtract
- ⊖ symmetric difference
- ⊆ subset
- ⊇ superset
$ npm install --save zet
const Zet = require('zet');
let a = new Zet([1, 2, 3]);
let b = new Zet([3, 4, 5]);
let c = new Zet([2, 3, 4]);
Zet.union(a, b);
//=> [Zet] {1, 2, 3, 4, 5}
a.union(b, c);
//=> [Zet] {1, 2, 3, 4, 5}
a.intersection(b);
//=> [Zet] {3}
a.symmetricDifference(c);
//=> [Zet] {1, 4}
a.subset(b);
//=> falseReturns:Zet
Returns the Zet instance.
Zet extends Set() and inherit all its functionality, like has(), size() etc.
Returns:zet
Static variadic function that return a new set with elements from all other sets.
Type: Zet|Set
Two or more sets of type Zet or Set.
Returns:zet
Static variadic function that return a new set with elements common to this and all other sets.
Type: Zet|Set
Two or more sets of type Zet or Set.
Returns:zet
Returns the difference between two or more sets. The order of the sets matters. Sets are differentiated against the first argument/set.
