• eqArrays(array1, array2): returns true if two passed arrays are equal, returns false if not
• assertArraysEqual(actual, expected): passes the two passed arrays into eqArrays, and if true is returned, console.logs a passed message, if false, passes a failed message
• eqObjects(object1, object2): returns true if two passed objects are equal, returns false if not
• assertObjectsEqual(actual, expected): passes the two passed objects into eqObjects, and if true is returned, console.logs a passed message, if false, passes a failed message
• head(array): returns the first element in a given array
• tail(array): returns all but the first element in a given array
• middle(array): returns the element(s) that are in the middle of a given array
• countLetters(string): returns an object with keys of letters with values of their count in a given string
• countOnly(allItems, itemsToCount): returns an object with keys of elements asked to be counted by a given object, and the count of how many times those elements occur within a given array as their values
• findKey(object, clallback): returns first key of a given value that matches a given function's value search criteria
• findKeyByValue(object, value): returns key of given object if it's value is equal to a given value
• flatten(array): returns a non-nested array version of a given nested array
• letterPositions(sentence): returns an object with keys of letters with values of an array containing each index of a given string that letter can be found at
• map(array, callback): returns an array of the return values of each element of a given array being passed into a given callback function
• takeUntil(array, callback): returns an array of each element of a given array until and element has met a stopping criteria given by the given callback method
