What's the difference between a function and a method in JavaScript?

You know what a function is, but you may have also heard the term method used before and wondered what it means.

So what’s the difference between a function and a method? Nothing. They’re the same thing.

In languages other than JavaScript, the two terms have specific meanings. And JavaScript developers will sometimes apply their own definition to the two terms.

The one I see most often is that a method is a function that’s inside an object like this.

var helperLibrar = {
	method1: function () {
		return 'This is a method, supposedly';
	}
};

The problem with these definitions is that no one agrees on them, and many, many JavaScript developers use function and method interchangeably.

In my opinion, they’re the same thing.
