This package is an extension of Immutable.js which provides
additional Persistent Immutable data structures SortedMap and SortedSet.
These data structures are highly efficient minimizing the need to copy or cache data by structural sharing via B-trees.
npm install immutable-sortedSortedSet (see more examples on SortedSet page):
> const { SortedSet } = require('immutable-sorted');
> const set1=SortedSet(['orange', 'apple', 'banana']);
SortedSet { "apple", "banana", "orange" }
> const set2=set1.add('mango');
SortedSet { "apple", "banana", "mango", "orange" }
> const set3=set2.delete('banana');
SortedSet { "apple", "mango", "orange" }SortedMap (see more examples on SortedMap page):
const { SortedMap, isSorted } = require('immutable-sorted');
> const map1=SortedMap([['orange','orange'], ['apple','red'], ['banana','yellow']]);
SortedMap { "apple": "red", "banana": "yellow", "orange": "orange" }
> const map2=map1.set('mango', 'yellow/orange');
SortedMap { "apple": "red", "banana": "yellow", "mango": "yellow/orange", "orange": "orange" }
> const map3=map2.delete('banana');
SortedMap { "apple": "red", "mango": "yellow/orange", "orange": "orange" }Modified work (Immutable Sorted collections) is MIT Licensed.
