• assertEqual: Checks if both input and output have a perfect match.
• head: : Returns the element at the 0th index of the given array.
• tail: Returns the rest of the array after removing the element at the 0th index.
• middle: Returns the middle element of an array.
• map: Returns a new array based on the results of the callback function.
• assertObjectsEqual: Detects if two objects are equal.
• countLetters: Returns a count of each of the letters in a given sentence.
• countOnly: Takes in an array and an object, and returns an object containing counts of everything listed in the input object.
