How to use Math.max, etc. as higher-order functions

Question

In short, this works:

[1, 2, 3].reduce(function (a, b) { return Math.max(a, b); });
=> 3

But this doesn\'t:

[1, 2, 3].re         


        

Answer 1

Math.max can be used as a higher-order function. The problem is .reduce will call the function with 4 arguments:

Math.max(accumulator, value, index, the_array)

here is the_array is an array, so Math.max returns NaN. I don't think there's simpler way to discard the last 2 arguments.
