unhandledrejection/rejectionhandled events

Last updated on : 2023-03-20

Note:
unhandledrejection/rejectionhandled events shows a browser compatibility score of 92. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

The rejectionhandled event is fired when a Promise has been rejected, but because some other RejectionHandling code has since caught and dealt with the rejection. The rejectionhandled event will not be fired if the Promise was never handled at all.
