arrayrandombeginnerReturns a random element from an array.

Use `Math.random()`

to generate a random number, multiply it by `length`

and round it off to the nearest whole number using `Math.floor()`

.
This method also works with strings.

const sample = arr => arr[Math.floor(Math.random() * arr.length)];
