kandi X-RAY | performance-timeline Summary
The PerformanceTimeline specification defines ways in which web developers can measure specific aspects of their web applications in order to make them faster. It introduces two main ways to obtain these measurements: via getter methods from the [Performance] interface and via the PerformanceObserver interface. The latter is the recommended way to reduce the performance impact of querying these measurements.

QUESTION
I figured out I can get the timings of the any XHR request from chrome using the performance API like this below which gives an array as an result (shows ho many requests of this resource has been made):
performance.getEntriesByType('resource').filter(item => item.name.includes("https://myurl"))
If I make 20 XHR requests parallely/concurrently, how do I differentiate which request performance is which object. Is there a way to get specific reference? I am using plain XHR request and am planning to use a RXJS stream if I am able to get a reference. Any help is welcome, I am new to this API. I have attached the request and the result screenshot below:
