Use Javascript and make sure you use recursive function please.

Write a function named `dynamicRotate(num)`. When invoked, the

`dynamicRotate` function will accept a number to be used as the

rotation amount and return a function. Positive numbers rotate

the array to the right and negative numbers rotate to the left.

The function returned by `dynamicRotate` will accept an array to

be rotated by the amount provided when `dynamicRotate` was

first invoked. It will return the original array mutated by

the given rotation.

Examples:

let arr = ['a', 'b', 'c', 'd', 'e'];

rotateRightTwo = dynamicRotate(2);

rotateRightTwo(arr);

console.log(arr); // [ 'd', 'e', 'a', 'b', 'c' ]

let animals = ['wombat', 'koala', 'opossum', 'kangaroo'];

rotateLeftOne = dynamicRotate(-1);

rotateLeftOne(animals)

console.log(animals); // [ 'koala', 'opossum', 'kangaroo', 'wombat' ]
