Explanation:

How to find largest number in JavaScript?

reduce() can be used to find the maximum element in a numeric array, by comparing each value:

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

function getMaxOfArray(numArray) { return Math. max. apply(null, numArray); } ...

var arr = [1, 2, 3]; var max = Math. max(... arr);
