Documentation

目前实现了以下功能：

• head(): returns the first element of an array
• tail(): returns a new array that contains all the elements of an inputted array expect for index0 ("the head of the inputted array")
• assertEqual(): returns a message for assertion pass or fail based on two arguments actual, expected
• eqArrays(): returns assertion after comparing two arrays (utilitzes assertEqual() for assertion)
• assertArraysEqual(): returns a console.log with appropriate assert message after comparing two arrays
• assertObjectsEqual(): prints an assertion method after comparing two objects
• countLetters(): returns an object that is the result of counting letters in a sentence (no spaces)
• countOnly(): returns an object that is the result of counting certain items in an array (based on criteria listed in another object)
• findKey(): returns key
• findKeyValue(): returns the name of the key that contains the value that is the same as an inputted one
• letterPositions(): returns an object that contains keys (letters in sentence) and values (indexes in which they appear in sentence)
• map(): loops over elements of an array, uses each element as a parameter for a CB function, pushes item into a new array
• middle(): returns the middle element(s) of an array (as an array; also contains assertion message)
• takeUntil(): returns elements in an array until the callback(element) is true.
• without(): returns a new array after removing items from a source array (takes in two arrays as parameters/arguments)
