How do I make my function anonymous in JavaScript?

In the code below I firstly try to print the 'normal' way. Secondly I try to anonymize my function and assign it to a variable which I then print. In Chrome this now proceeds to print the source code. What am I doing wrong?

function sumSq() {
    var  sum = 0;
    for (i=0;i<=10;i++) {
        sum+=i*i;
    }
    return sum;
}
console.log(sumSq());

var mySum = function() {
    var  sum = 0;
    for (i=0;i<=10;i++) {
        sum+=i*i;
    }
    return sum;
}
console.log(mySum);

var mySum = function() {
    var  sum = 0;
    for (i=0;i<=10;i++) {
        sum+=i*i;
    }
    return sum;
}

is just the same with:

function mySum() {
    var  sum = 0;
    for (i=0;i<=10;i++) {
        sum+=i*i;
    }
    return sum;
}

And call it console.log(mySum());

Call mySum using ():

console.log(mySum());

Functions are objects, so when you call

console.log(mySum);

JS calls toString on the mySum object (which mySum inherits from the Object prototype). That's why the source gets printed.

Function should be called as mySum()

Apart from this, both ways do the same.
