Documentation

The following functions are currently implemented:

• head(..): Gets the first element of array.
• tail(..): Gets all but the first element of array.
• middle(..): Implement middle which will take in an array and return the middle-most element(s) of the given array.
• assertArraysEqual(..): Implement assertArraysEqual which will take in two arrays and console.log an appropriate message to the console.
• assertEqual(..) : If the values match, it should print (console.log) the following: Assertion Passed: actual === expected (but with the values filled in) Otherwise it should print (console.log) the following: Assertion Failed: actual !== expected (but with the values filled in).
• assertObjectsEqual(..)
• countLetters(..): The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(..): This function should take in a collection of items and return counts for a specific subset of those items.
• eqArrays(..): Implement a function eqArrays which takes in two arrays and returns true or false, based on a perfect match.
• eqObject(..)
• findKey(..)
• findKeyByValue(..): takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• letterPositions(..): function letterPositions which will return all the indices (zero-based positions) in the string where each character is found.
• map(..): Returns the first letter of each element in an array of strings.
• takeUntil(..):Takes an array and a callback function. Returns a new array of items occuring until the point specified by the callback functions.
• without(..): Implement without which will return a subset of a given array, removing unwanted elements.
