• assertEqual(actual, expected): Will take two arguments and output if they match or not.
• assertObjectsEqual(actual, expected): will take in two objects and console.log an appropriate message to the console.
• countLetters(string): This function take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): allItems: an array of strings that we need to look through. itemsToCount: an object specifying what to count
• eqArrays(array1, array2): A function eqArrays which takes in two arrays and returns true or false, based on a perfect match.
• eqObjects(object1, object2): Will take in two objects and returns true or false, based on a perfect match.
• findKey(object1, callback): takes in an object and a callback.
• flatten(arrayToFlat): a function flatten which will take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• head(name): A function that will take the first element of an array.
