• function middle(...): returns an array one with either one middle element or two middle elements for a given array with odd or even number of elements accordingly
• function assertArraysEqual (...): takes in two arrays and logs an appropriate message to the console
• function assertEqual(...): compares the two values it takes in and print out a message telling us if they match or not
• function assertObjectsEqual(...): takes in two objects and console.log an appropriate message to the console
• function countLetters (...): takes in a string and returns a count of each of the letters in the string
• function countOnly(...): takes in a collection of items and returns counts for a specific subset of those items
• function eqArrays(...): takes in two arrays and returns true or false, based on a perfect match
• function eqObjects (...): take in two objects and returns true or false, based on a perfect match (checks primitive return types only)
• function findKey(...): takes in an object and a callback, scans the object and returns the first key for which the callback returns a truthy value
• function findKeyByValue(...): searches for a key on an object where its value matches a given value
• function letterPositions (...): returns all the indices in the string where each character is found
• function map(...): takes an array and a callback function and returns a new array based on the results of the callback function
• function takeUntil(...): collects items from a provided array until the callback provided returns a truthy value
