The following functions are currently implemented:

• head(array): takes an array and returns the first element
• tail(array): takes an array and returns the array without the first element
• middle(array): takes an array and returns the middle element (middle two elements for an even array)
• assertArraysEqual(actualArray, expectedArray): prints to console whether two arrays are equal
• assertEqual(actual, expected): prints to console whether two values are equal
• assertObjectsEqual(ActualObj, expectedObj): prints to console whether two objects are equal
• countLetters(string): returns the number of each letter in a given string
• countOnly(array, objectToCount): returns an object of the occurences from the given array of the keys to find which are indicated in the given object
• eqArrays(array1, array2): returns true or false depending on whether the given arrays are equal
• eqObjects(object1, object2):returns true or false depending on whether the given objects are equal
• findKey(object, criteriaFunction): returns the key of the first occurence of the given criteria function returning true for a given objects keys
• findKeyByValue(object, Value): returns the key of a given object which has a value matching the given value
• flatten(array): returns an array which un-nests one level of nested arrays
• letterPositions(sentence): returns an object containing arrays of all the indexes of each letter's occurence in a given sentence (string)
• map(array, callback): takes an array and a function and returns a new array with the function applied to each element
• takeUntil(array, callback): copies an array element by element until the given callback function returns true
• without(array, toRemove): takes an array and an array with values to remove and returns a new array which does not include any elements matching the elements in the toRemove array
