• middle(arr): returns the middle 1 or 2 indexes of an array
• without(source, itemsToRemove): removes items from an array
• takeUntil(array, callback): recreates array until specified input is reached
• ourMap(array, callbackFunction): returns an array of the same length as the input
• letterPositions(string): returns the index of a string
• findKeyByValue(searchObject, keyValue): finds object key by it's corresponding value
• findKey(object, callback): finds key in object
• eqObjects(object1, object2): tests object equality
• eqArrays(arr1, arr2): tests array equality
• countOnly(allItems, itemsToCount): counts only desired elements of an array
• countLetters(string): returns an object of letter quantity
• assertObjectsEqual(obj1, obj2): tests object equality
• assertEqual(actual, expected): tests equality of primitive variables
• assertArraysEqual(arr1, arr2): tests array equality
