• assertArraysEqual(arrayOne, arrayTwo) : takes in 2 arrays and returns true if they are equal and false otherwise
• assertEqual(actual, expected) : takes in 2 values and returns true if they are equal and false otherwise
• assertObjectsEqual(objOne, objTwo) : takes in 2 objects and returns true if they are equal and false otherwise
• countLetters(word) : takes in a sentence and returns a count of each of the letters in the sentence
• countOnly(allItems, itemsToCount) : takes in a collection of items and returns a specific subset of those items
• eqArrays(firstArray, secondArray) : takes in 2 arrays and returns true if the arrays are equal and false otherwise
• eqObjects(object1, object2) : takes in 2 objects and return true if they are equal and false otherwise
