forEachAsync(iterable, callback, options)	`static`	Given an input array and a `callback` function, invoke the callback to start a promise for each element in the array.
getSignal()	`static`	Returns a Signal, a.k.a. a "deferred promise".
mapAsync(iterable, callback, options)	`static`	Given an input array and a `callback` function, invoke the callback to start a promise for each element in the array. Returns an array containing the results.
mapAsync(iterable, callback, options)	`static`	Given an input array and a `callback` function, invoke the callback to start a promise for each element in the array. Returns an array containing the results.
runWithRetriesAsync({ action, maxRetries, retryDelayMs }, input)	`static`	Executes an async function and optionally retries it if it fails.
runWithTimeoutAsync({ action, timeoutMs, timeoutMessage }, input)	`static`	Runs a promise with a timeout. If the promise does not resolve within the specified timeout, it will reject with an error.
