# Math.max()

The `Math.max()` function returns the largest of the numbers given as input parameters, or -`Infinity` if there are no parameters.

## Syntax

``````Math.max()
Math.max(value0)
Math.max(value0, value1)
Math.max(value0, value1, /* … ,*/ valueN)
``````

### Parameters

`value1`, `value2`, … , `valueN`

Zero or more numbers among which the largest value will be selected and returned.

### Return value

The largest of the given numbers. Returns `NaN` if any of the parameters is or is converted into `NaN`. Returns -`Infinity` if no parameters are provided.

## 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).

`Math.max.length` is 2, which weakly signals that it's designed to handle at least two parameters.

## Examples

### Using Math.max()

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

### Getting the maximum element of an array

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

``````const arr = [1, 2, 3];
const max = arr.reduce((a, b) => Math.max(a, b), -Infinity);
``````

The following function uses `Function.prototype.apply()` to get the maximum of an array. `getMaxOfArray([1, 2, 3])` is equivalent to `Math.max(1, 2, 3)`, but you can use `getMaxOfArray()` on programmatically constructed arrays. This should only be used for arrays with relatively few elements.

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

The spread syntax is a shorter way of writing the `apply` solution to get the maximum of an array:

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

However, both spread (`...`) and `apply` will either fail or return the wrong result if the array has too many elements, because they try to pass the array elements as function parameters. See Using apply and built-in functions for more details. The `reduce` solution does not have this problem.
