# Heap happens

Need a fast and efficient heap/priority queue in your JavaScript/TypeScript projects? Look no further!

This package offers a simple, flexible, and performant implementation of the Heap data structure, ready to tackle your most demanding tasks.

## Examples

Push, top and change higher priority comparator method.

```ts
const heap = new Heap<number>();

heap.push(404);
heap.push(200);
heap.push(500);

console.log(heap.top()); // 500
heap.changeHigherPriorityComparator((a, b) => a < b);
console.log(heap.top()); // 200
```

Default custom comparator and toSortedArray method.

```ts
const heap = new Heap<Profile>({
comparator: (a, b) => a.points > b.points
// if a.points is greater than b.points, then 'a' has higher priority
});

heap.push({ name: "Avi", points: 500 });
heap.push({ name: "Foo", points: 900 });
heap.push({ name: "Bar", points: 700 });

console.log(heap.top()); // { name: "Foo", points: 900 }
console.log(heap.toSortedArray(profile => profile.name)); // ["Foo", "Bar", "Avi"]
```
