What is the purpose of the timing property in the window.performance object? Correct Answer Time of navigation and page load event

Each performance.timing attribute shows the time of a navigation event (such as when the page was requested) or page load event (such as when the DOM began loading), measured in milliseconds. The legacy Performance.timing read-only property returns a PerformanceTiming object containing latency-related performance information.
