We need to generate a random integer value from `0` to `arr.length-1`, and then take the element with that index.
|
||||
|
||||
Here we go:
|
||||
|
||||
```js run
|
||||
let arr = ["Apple", "Orange", "Pear", "Lemon"];
|
||||
|
||||
let rand = Math.floor(Math.random() * arr.length);
|
||||
|
||||
alert( arr[rand] );
|
||||
```

|
||||
|
||||
```js
|
||||
let arr = ["Apple", "Orange", "Pear", "Lemon"];
|
||||
```
