Window: performance property

{{APIRef("Performance API")}}

The performance property of the {{domxref("Window")}} interface returns a {{domxref("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 {{domxref("Performance")}} object offering access to performance and timing-related information about code running in the window's scope.
