PerformanceScriptTiming: pauseDuration property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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

The pauseDuration read-only property of the PerformanceScriptTiming interface returns a DOMHighResTimeStamp indicating the total time, in milliseconds, spent by the script on "pausing" synchronous operations (for example, Window.alert() calls or synchronous XMLHttpRequests).
