¿Do you know how to onload a script using the onload method?

Question

This is very helpful when you want to execute an script after the whole page has loaded.

Note: my English is not very good, sorry.

Answer 1

window.addEventListener('DOMContentLoaded', () => {
console.log('page loaded');
});

Answer 2

Classic JS way:

window.onload = function() {
myFunction();
}

function myFunction() {
alert("Hey! I'm myFunction. I'm invoked by load event handler");
}

Others can give you example of it with modern JS later on.
