-Wrap an [async](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function)/[promise-returning](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises)/`sync` function as a queue-ready async function, which is enqueued while being called. This is convenient to reuse it. Task queues execute original functions sequentially by default (synchronization mode, `concurrency limit = 1`) and allow changing concurrency limit to have concurrent tasks executed. It also supports `@synchronized` [decorator](https://www.typescriptlang.org/docs/handbook/decorators.html) on instance or static methods. Passing arguments and using `await` to get return values are also supported.
