Window: performance property
The performance property of the Window interface returns a Performance object, which can be used to gather performance information about code running in the window's scope.
Performance entries are per context. If you create a mark on the main thread (or other worker), you cannot see it in a worker thread, and vice versa.
Value
A Performance object offering access to performance and timing-related information about code running in the window's scope.
