LoAF scripts attribution test

gistfile1.txt

// go to chrome://flags/ and enable Experimental Web Platform features flag

// Add a logger for LoAF entries
const observer = new PerformanceObserver(function(list) {
    for (const entry of list.getEntries()) { console.log(entry)  }
});

observer.observe({type: "long-animation-frame", buffered: true});

// Define a slow and fast function. The slow function here is the precise source of our performance bottleneck
function slow(){
    let start = performance.now()
    while(performance.now() - start < 1e3){}
}

function fast(){
    slow();
}

// Add fast() call somewhere in your UI, what does scripts attribute of the logged entry represent?
