# length property

The `length` property allows you to find out and set the length of an array.

## Syntax

`array.length;`

## Example

Let's output the length of the array `arr`:

`let arr = ['a', 'b', 'c', 'd', 'e']; console.log(arr.length);`

The code execution result:

`5`

## Example

Let's reduce the array to `2` elements:

`let arr = ['a', 'b', 'c', 'd', 'e']; arr.length = 2; console.log(arr);`

The code execution result:

`['a', 'b']`
