• assertArraysEqual(arr1, arr2): checks if two arrays are equal
• assertEqual(actual, expected): checks if two numbers or strings are equal
• assertObjectsEqual(actual, expected): checks if two objects are equal
• countLetters(string): counts a specified letter in a string and returns the number of times it appears
• countOnly(allItems, itemsToCount): returns how many instances of each string were found in the array of strings
• eqArrays(arr1, arr2): checks if two arrays are equal
• eqObjects(object1, object2): checks if two objects are equal
• findKey(object, callback): returns the first key for which the callback returns a truthy value
• findKeyByValue(objectToScan, value): returns the first key which contains a given value
