A timestamp
representing the time value equal to the time immediately before the user agent fires the DOMContentLoaded event at the current document.
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);
}
