## Array Length
|
||
|
|
|
||
|
|
`length` is a property of arrays in JavaScript that returns or sets the number of elements in a given array.
|
||
|
|
|
||
|
|
The `length` property of an array can be returned like so.
|
||
|
|
|
||
|
|
```js
|
||
|
|
let desserts = ["Cake", "Pie", "Brownies"];
|
||
|
|
console.log(desserts.length); // 3
|
||
|
|
```
|
||
|
|
The assignment operator, in conjunction with the `length` property, can be used to set then number of elements in an array like so.
|
||
|
|
|
||
|
|
```js
|
||
|
|
let cars = ["Saab", "BMW", "Volvo"];
|
||
|
|
cars.length = 2;
|
||
|
|
console.log(cars.length); // 2
|
||
|
|
```
|
