    Math.max()

    Summary

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

    Syntax

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

    Parameters

    value1, value2, ...
    Numbers.

    Description

    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 (Math is not a constructor).

    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.

    Examples

    Example: Using Math.max()

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

    The following function uses Function.prototype.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);
    }
