PerformanceResourceTiming class
The interface enables retrieval and analysis of detailed network
timing data regarding the loading of an application's resources.
An application can use the timing metrics to determine, for
example, the length of time it takes to fetch a specific
resource, such as an XMLHttpRequest, <SVG>, image, or script.
The interface's properties create a resource loading timeline
with high-resolution timestamps for network events such as
redirect start and end times, fetch start, DNS lookup start and
end times, response start and end times, etc.. Additionally, the
interface extends PerformanceEntry with other properties which
provide data about the size of the fetched resource as well as
the type of resource that initiated the fetch.
