        counter.innerText = 0;

        const updateCounter = () => {

            const c = +counter.innerText;
            const increment = target / 200;

            if (c < target) {
                counter.innerText = Math.ceil(c + increment);
                setTimeout(updateCounter, 1);
                // here the function is calling itself until "c"
                // reaches the "data-target", making it recursive
            } else {
                counter.innerText = target;
            }
        };

        updateCounter();
    });

document.addEventListener('DOMContentLoaded', incrementStats);

COPY

This will display a counter, starting (currently set to 0) up to data-target in increments of (data-target / 200), each increment/loop set, via setTimout to 1ms. It first brings in all .counter elements.

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;
}
