Documentation

The following functions are currently implemented:

* head([arr]) : Accepts array as an argument and returns its first element.

head([]) => undefined;
head([1]) => 1;
head([4,2,3,6]) => 4;
head("notArr") => undefined;

* middle([arr]) : Accepts array as an argument and return its middle element

//Returns an empty array for arrays with equal to or less than two element
middle([]) => [];
middle([1]) => [];
middle([1,2]) => [];

// Returns a single middle element for array with odd number of elements. 
middle([1, 2, 3]) // => [2]
middle([1, 2, 3, 4, 5]) // => [3]

// Returns an array containing the two elements in the middle for array with even number of elements.
middle([1, 2, 3, 4]) // => [2, 3]
middle([1, 2, 3, 4, 5, 6]) // => [3, 4]

* tail([arr]) : Returns everything except the first element of the provided array.

const words = ["Yo Yo", "Lighthouse", "Labs", "Val"];
tail(words) => ["Lighthouse", "Labs", "Val"];
words.length === 3;

// Returns undefined for arrays with length less than or equal to 1
tail(["lorem"]) => undefined;
tail([]) => undefined;
