Javascript function returning the function itself?

Question

I have a small bit of code that is really giving me a headache. All it needs to do is get a location (in this case an array representing a longitude and latitude).

planner.js:

var plan = function (lawnmower, yard) {
var currentPos = lawnmower.position;
alert(currentLong);

lawnmower:

var longitude = homeLongitude, latitude = homeLatitude;
var getPosition = function() {
    return [longitude, latitude];
};
that.position = getPosition;

When the alert gets called it returns getPosition after the equal sign.

Heres a pic

I'm fairly novice at JS.

You are assigning the value of the function as opposed to assigning the result of it's invocation, which is represented by the (). — rgbchris

You forgot the () when you call getPosition, so instead of assigning the result to that.position you're assigning the entire function:

that.position = getPosition(); //parenthesis!
