Question

What kind of function is this, and how do I call it:

window.bla = function() {}

Is it the same as an on-load function or is it the same as prototyping..?

Answer 1

It’s neither, it’s just a global variable with the name bla. It’d be the same as bla = function() {}.

Prototyping looks like this:

var Example = function() {
    return this;
};

Example.prototype.bla = function() {};

On-load looks like this:

window.onload = function() {
    // stuff here
};
