Node.JS - Handling Certain Types of Promise Rejections?

In Node.JS, I know that you can use the unhandledRejection event to catch unhandled errors. However, I only want to catch a certain type of error. How can I do this?

From unhandledRejection node.js docs:

The listener function is called with the following arguments:

reason | The object with which the promise was rejected (typically an Error object).

p the Promise that was rejected.

So, you can check the event reason... ex.:

 if (evt.reason === 'Some specific Error') {
 // do something
