Retrieve the OrderedSet
constructor and use the methods:
const { OrderedSet } = require("@humanwhocodes/ordered-set");
// create a new instance
const set = new OrderedSet();
// add in data
set.add(1);
set.add(2);
set.add(3);
// get the value before 2
const prev = set.previous(2);
// get the value after 1
const next = set.next(1);
// check if a value exists in the set
const exists = set.has(2);
// how many values are in the set?
const size = set.size;
// get the first value in the set
const first = set.first();
// get the last value in the set
const last = set.last();
// find the next value matching this function
const value1 = set.findNext(value => value > 1, 1);
// find the previous value matching this function
const value2 = set.findPrevious(value => value > 1, 3);
// remove a value
set.delete(1);
// get all values
let values1 = [...set.values()];
let values2 = [...set];
// get all values in reverse order
let values3 = [...set.reverse()];
