JavaScript What does it mean to pass `undefined` to bind()?

I was reading some documentation about the bind() function in javascript.

One of the examples starts off like this:

function list() {
  return Array.prototype.slice.call(arguments);
}

var list1 = list(1, 2, 3); // [1, 2, 3]

//  Create a function with a preset leading argument
var leadingZeroList = list.bind(undefined, 37);

var list2 = leadingZeroList(); // [37]

So my question is:

What exactly does it means to pass (undefined, 37) to bind() here?
