[JavaScript] How to get a random element from an array?

Using `Math.floor(Math.random() * array.length)`, we can generate a random number of length less than Array size and we can use that as index to pick a random element from array. Following code shows how to do that

```js
let numbers = [10,20,30,40,50,60,70,80];
console.log(numbers[Math.floor(Math.random() * numbers.length)])
```
