Returns all elements in an array except for the first one.

Return Array.prototype.slice(1) if the array's length is more than 1, otherwise, return the whole array.

typescript
const tail = (arr: any[]) => (arr.length > 1 ? arr.slice(1) : arr);
typescript
tail([1, 2, 3]); // [2,3]
tail([1]); // [1]
