Here are some methods to calculate code execution time in jQuery.
1. Using console.time(label), console.timeEnd(label)
function sayHello(i){
console.log(i, 'Hello world!');
}
// Start the timer with label "codeTimer"
console.time("codeTimer");
// Code being timed
for (let index = 0; index < 100; index++) {
sayHello(index);
}
// Stop the timer and logs the elapsed time with the same label "codeTimer"
console.timeEnd("codeTimer");
2.Using Date
//Set start point where you want
var start = new Date();
// Code being timed
for (let index = 0; index < 10000; index++) {
sayHello(index);
}
//Set end point where you want
var end = new Date();
//Get the elapsed time in milliseconds
var duration = end - start;
console.log('Code execution took', duration, 'milliseconds')
3. Using performance
// Take a timestamp at the beginning before executing the code being timed
var start = performance.now();
// Code being timed
for (let index = 0; index < 10000; index++) {
sayHello(index);
}
// Take a final timestamp to stop time measurement
var end = performance.now();
//Get the elapsed time in milliseconds
var duration = end - start;
console.log('Code execution took', duration, 'milliseconds')
