TaskAttributionTiming

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The TaskAttributionTiming interface of the Long Tasks API returns information about the work involved in a long task and its associate frame context. The frame context, also called the container, is the iframe, embed or object that is being implicated, on the whole, for a long task.
