• head(array): returns the first element of an array

• tail(array): returns the end of an array excluding the first element

• middle(array): returns the middle-most element of a given array

• map(array, callback): returns a new array with the results of performsing a callback function on each element of array passed to it

• letterPositions(sentence): takes in a string and returns all indices in the string where each character is found

• findKey(object, callback): scans a given object and returns the first key for which a given callback returns a truthy value

• countOnly(allItems, itemToCount): takes in a array of items and returns a count for a specific subset of items specified with a given object

• countLetters(sentence): takes in a string and returns a count of each of the letters in the string

• without(source, itemsToRemove): takes in a source array and itemsToRemove array and returns a filtered source array without any element from the itemsToRemove array

• takeUntil(array, callback): takes in an array and returns a slice of the array with callback function performed on each element from the beginning until callback function returns truthy value

• findKeyByValue(objectToScan, valueToFind): takes in an object to scan and returns the first key which matches a given value

• assertEqual(actual, expected): logs message to console stating if actual is equal to expected

• assertArraysEqual(arr1, arr2): logs message to console stating if 2 arrays are equal

• assertObjectsEqual(actual, expected): logs message to console stating if 2 objects are equal

• eqArrays(arr1, arr2): checks if given arrays are equal and returns boolean

• eqObjects(object1, object2): checks if given objects are equal and returns boolean
