# Avoid Promise.any

In workflow-js, you can use [`Promise.all` to run steps in parallel](/workflow/howto/parallel-runs). However, a similar method, [`Promise.any`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/any), is not supported for workflow steps.

While `Promise.all` works seamlessly, `Promise.any` does not currently function with workflow steps. We are exploring the possibility of adding support for `Promise.any` in the future.

If you have a specific use case that requires `Promise.any`, don't hesitate to reach out to Upstash support.
