# Math.max()

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

## Syntax

Math.max([<var>value1</var>[, <var>value2</var>[, ...]]])

### Parameters

`value1, value2, ...`

- Numbers.

### Return value

The largest of the given numbers. If at least one of the arguments cannot be converted to a number, `NaN`

is returned.

## 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

### 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); }

Or with the new `spread operator`

, getting the maximum of an array becomes a lot easier.

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