This project is part of the @thi.ng/umbrella monorepo.

About

Type agnostic binary heap & d-ary heap implementations with customizable ordering and fanout / tree arity (in case of DHeap). Both Heap and DHeap have identical base API, however the former provides several additional operations.

Usage examples

import { Heap, DHeap } from "@thi.ng/heaps";

// with initial values, custom comparator and heap arity
const h = new DHeap(
    [5, 2, 10, 15, 18, 23, 22, -1],
    {
        compare: (a,b) => b - a,
        d: 4
    }
);

h.pop();
// 23
h.pop();
// 22

// insert new value unless it's a new root
// else pop and return current root
h.pushPop(16)
// 18

h.push(24);
