Updated helper to be nestable: function start(task, isOuterCancelled = null) { let cancelled = false; function isCancelled() { return isOuterCancelled?.() || cancelled; } function nestedStart(task) { start(task, isCancelled); } function check(promise) { if (isCancelled()) { return new Promise(() => {}); } return promise; } return { promise: task(check, nestedStart), cancel() { cancelled = true; }, }; }
