var t0 = performance.now();

for (let i = 0; i < 10000; i++) {   
    // Do stuff here 
}  

// Do some other stuff here

var t1 = performance.now();
console.log("Call to doSomething took " + (t1 - t0) + " ms.")

COPY

Sometimes we need to calculate the time taken by a piece of code to complete execution. The performance.now() can be used to compute the execution time.

How to Get the Domain From A URL Using Javascript

Required Parameters for Functions in JavaScript

 const isRequired = () => { throw new Error('param is required'); };

const hello = (name = isRequired()) => { console.log(`hello ${name}`) };

// These will throw errors
hello();
hello(undefined);

// These will not
hello(null);
hello('David');
The idea here is that it uses default parameters, like how the b parameter here has a default if you don’t send it anything:
function multiply(a, b = 1) {
  return a * b;
}
