A timestamp
representing a time value equal to the time immediately before the load event of the current document is fired.
The following example illustrates this property's usage.
function print_nav_timing_data() {
var perfEntries = performance.getEntriesByType("navigation");
for (var i=0; i < perfEntries.length; i++) {
console.log("= Navigation entry[" + i + "]");
var p = perfEntries[i];
console.log("DOM content loaded = " + (p.domContentLoadedEventEnd - p.domContentLoadedEventStart));
console.log("DOM complete = " + p.domComplete);
console.log("DOM interactive = " + p.interactive);
console.log("document load = " + (p.loadEventEnd - p.loadEventStart));
console.log("document unload = " + (p.unloadEventEnd - p.unloadEventStart));
console.log("type = " + p.type);
console.log("redirectCount = " + p.redirectCount);
}
