The Math.max() function returns the largest of zero or more numbers.


Math.max([value1[,value2, ...]]) 


value1, value2, ...


Because max is a static method of Math, you always use it as Math.max(), rather than as a method of a Math object you created.

If no arguments are given, the result is - Infinity.

If at least one of arguments cannot be converted to a number, the result is NaN.


Example: Using Math.max

Math.max(10, 20);   //  20
Math.max(-10, -20); // -10
Math.max(-10, 20);  //  20

The following function uses apply to find the maximum element in a numeric array. getMaxOfArray([1,2,3]) is equivalent to Math.max(1, 2, 3), but you can use getMaxOfArray on programmatically constructed arrays of any size.

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