Math.min.apply(0, array) - why?

Question

I was just digging through some JavaScript code (Raphaël.js) and came across the following line (translated slightly):

Math.min.apply(0, x)

Answer 1

The proper and less confusing way to call this is: Math.min.apply(null, array)

If parameter is unused setting it to null makes code more readable than setting it to 0 or Math
