# Type
|
|
|
|
|
|
|
|
|
|
In JavaScript arrays are a type of [object](20200826201605-objects) that
|
|
|
|
|
store sequences of things. `typeof` wil therefore return "object"
|
|

|
|
|
|
|
|
|
``` javascript
|
|
|
|
|
let listOfThings = ["Car", "Mr Magoo", 42];
|
|
|
|
|
|
|
|
|
|
console.log(typeof listOfThings); // object
|
|
|
|
|
```
