Locking primitives for TypeScript

Locking primitives for TypeScript

This module provides various locking primitives for modern TypeScript:

import {Semaphore} from "@mdekstrand/locks";
const lock = new Semaphore(2);

function myContentiousTask() {
    using _lock = await lock.acquire();
    // do the work
    // the lock is automatically released at end of function!
}

It is heavily inspired by asyncutil, particularly in its API, with my own take on the ideas and a focus on simplicity and safety over extremes in performance (but it does try to avoid unnecessarily inefficient constructs).

It has a single dependency — deque, a TypeScript port of denque, used to implement Notify (which in turn is used to implement many other elements).
