• middle(array): take in an array and return the middle-most element(s) of the given array.
• tail(array): returns everything except for the first item (head) of the provided array.
• assertEqual(actual, expected): compares strings
• eqArrays(arr1, arr2): takes in two arrays and returns true if they are === equal
• assertArraysEqual(actual, expected): compares arrays
• eqObjects(obj1, obj2): take in two objects and returns true if they are === equal
• assertObjectsEqual(actual, expected): compares objects
• countLetters(string): takes in a string and returns an object containing letters and their frequency within string
• letterPositions(sentence): takes in a sentence and returns letters and all their corresponding indices
• findKey(object, callback): looks for a value that makes the callback function truthy and returns its key, else undefined.
• findKeyByValue(object, value): iterates through an object and looks for the desired value and returns the key.
• map(array, callback): takes in an array and applies the callback function to all elements and returns an array
