I checked the W3C web page but I dont fully understand the difference in the following 2:
- performance.timing.navigationStart
" This attribute must return the time immediately after the user agent finishes prompting to unload the previous document. If there is no previous document, this attribute must return the time the current document is created. "
2 window.performance.timing
" The timing attribute represents the timing information related to the browsing contexts since the last non-redirect navigation. This attribute is defined by the PerformanceTiming interface. "
I dont fully understand these mean. Can someone explain this in detail?
