How can I measure execution time in JavaScript?

How can I measure execution time in JavaScript?

You can use the console.time() and console.timeEnd() methods to measure execution time. Just wrap your code between these two calls.

Can you show me an example?

Sure! Here's a simple example:

console.time('myFunction');
// Your code here
console.timeEnd('myFunction');

What if I want to measure multiple functions?

You can use different labels for each function. For example:

console.time('function1');
// function1 code
console.timeEnd('function1');

console.time('function2');
// function2 code
console.timeEnd('function2');

Is there a way to measure execution time in a more detailed way?

Yes! You can use the performance.now() method for more precise measurements. It gives you time in milliseconds with sub-millisecond precision.
