The following functions are currently implemented:

• head: retrieves the first element of an array.
• tail: retrieves all elements of an array except the first.
• middle: retrieved the middle element of an array and where the number of elements are even, it provides an average of the two middle numbers. Where an array contains zero, one or two elements, it returns an empty array.
• without: the function takes in two paramenters; parameter 1 being an array and parameter 2 being an array of items to be filtered out of parameter 1. it returns a new array with only elements not removed from the original array.
• countOnly: this function takes in 2 parameters. parameter 1 which is a collection of items and parameter 2 which are the items we want to count. It returns counts for the items specified to be counted. Where an item to count is not included in the the list in parameter 1, it returns undefined.
