ObservableSet

ObservableSet is an observable wrapper over a JavaScript Set. It allows Twist to detect when the contents of the set changes, so that reactivity works as expected.

NOTE: ObservableSet is not currently iterable from JavaScript, unlike a Set - this capability will be added in future.

Constructor

The constructor can optionally be supplied a Set, or an Iterable object:

import { ObservableSet } from '@twist/core';

var set1 = new ObservableSet;
console.log(set1.size); // 0

var set2 = new ObservableSet([ 1, 2, 3, 3 ]);
console.log(set2.size); // 3 (sets can't contain duplicates)

var set3 = new ObservableSet(new Set([ 1, 2 ]));
console.log(set3.size); // 2
