Documentation

目前实现了以下功能：

• assertArraysEqual = function(actual, expected): Takes in two arrays and console.logs whether those arrays match.
• assertEqual = function(actual, expected): Asserts whether two arrays are equal.
• assertObjectsEqual = function(actual, expected: Takes in two objects and console.logs whether those arrays match.
• countLetters = function(string): Counts letters in a string.
• countOnly = function(allItems, itemsToCount): Counts specific items in an array.
• eqArrays = function(array1, array2): Can compare two arrays for a perfect match.
• eqObjects = function(object1, object2): Takes in two objects and returns true or false, based on a perfect match.
• findKey = function(object, callback): Takes in an object and a callback, returning the first key that the callback returns truthy.
• findKeyByValue = function(object, value): Takes in an object and returns the first key which contains the given value.
• flatten = function(array): Takes in an array of arrays and returns a flattened version.
• head = function(array): Returns the first item in an array.
• letterPositions = function(sentence): Returns all the indices (zero-based positions) in the string where each character is found.
• map = function(array, callback): Creates a new array with the results of calling a provided function on every element in the calling array.
• middle = function(array): Returns the middle element of an array.
• tail = function(array): Returns every element in an array except for the head.
• takeUntil = function(array, callback): Returns a slice of an array until callback returns a truthy value.
• without = function(source, itemsToRemove): Returns a new array with only elements that are not present in the second array when compared to the first.
