• assertArraysEqual(actual, expected): prints success/failure message after comparing actual and expected, but is meant for an array
• assertEqual(actual, expected): prints success/failure message after comparing actual and expected
• assertObjectsEqual(actual, expected): takes in two objects and console.logs an appropriate message to the console
• countLetters(str): takes in a sentence (as a string) and then returns a count of each of the letters in that sentence
• countOnly(allItems, itemsToCount): takes in a collection of items and returns counts for a specific subset of those items
• eqArrays(array1, array2): compares arrays
• eqObjects(object1, object2): takes in two objects and returns true or false, based on a perfect match
• findKey(obj, callback): takes in an object and a callback and returns the first key for which the callback returns a truthy value
• findKeyByValue(obj, objValue): takes in an object and a value, and returns the first object key which contains the given value
• flatten(array): flattens array into single-level
• head(array): retrieves first element from array
• letterPositions(sentence): returns all the indices in the string where each character is found
• map(array, callback): returns a new array based on the results of the callback function
• middle(array): returns the middle-most element(s) of the given array
• tail(array): retrieves every element except the head
• takeUntil(array, callback): returns a slice of the array with elements taken from the beginning
