The following functions are currently implemented:

• assertArraysEqual(arrOne, arrTwo): logs whether two arrays are equal.
• assertEqual(actual, expected): Asserts whether two primitive values are equal.
• assertObjectsEqual(objOne, objTwo): Asserts whether two objects are equal.
• countLetters(str): Returns how many times a letter is in a string.
• countOnly(allItems, itemsToCount): Returns how many times items (itemsToCount) appears in a list (allItems).
• eqArrays(arrOne, arrTwo): Compares the data of two arrays to check if they are equal to each other.
• eqObjects(objOne, objTwo): Compares the data of two objects to check if they are equal to each other.
• findKey(obj, cal): Given an object with values containing another object, using a callback, it will return the first key matching the callback.
• findKeyByValue(object, value): Returns the key of an object matching value arg.
• flatten(arr): Given an array with nested arrays no more than 1 level deep, will return simple none nested array with all values in it.
• head(array): Returns the first item in an array.
• letterPositions(str): Given a sentence, and the letter you want the indexes of, it will return an array with the indexes of that letter.
• map(array, callback): Iterates over an passed array and returns a new array with values based of a passed callback.
• middle(arr): Returns an array of the middle value of an array. If even numbered array, will return the middle 2 values of that array.
• tail(arr): Returns an array with every value after the first item in that array.
• takeUntil(array, callback): Returns an array with every value until callback is met.
• without(source, itemsToRemove): Given an array of items, and an array of items you want removed, returns a new array with remaining items.
