Use AbortController to implement custom async task cancelling logic. Expounded upon here: https://cameronnokes.com/blog/cancelling-async-tasks-with-abortcontroller/

wait-with-abortsignal.js

function wait(ms, opts = {}) {
  return new Promise((resolve, reject) => {
    let timerId = setTimeout(resolve, ms);
    if (opts.signal) {
      // implement aborting logic for our async operation
      opts.signal.addEventListener('abort', event => {
        clearTimeout(timerId);
        reject(event);
      });
    }
  });
}

let abortController = new AbortController();

wait(100, { signal: abortController.signal })
  .then(() => console.log('wait complete'))
  // catch the aborted promise rejection in here
  .catch(console.error);

abortController.abort();

// => Error: Event { type: 'abort', ... }

You don't clean up the event handler when wait returns normally (not aborted) which is a memory leak.
