• assertEqual(actual, expected):

  • function that compares two values and prints out a message if they match or not

• assertObjectsEqual(object1, object2):

  • function that takes in 2 objects and returns true if they are equal and false otherwise

• countLetters(string):

  • function that takes in a sentence and returns a count of each of the letters in the sentence

• countOnly(allItems, itemsToCount):

  • function that takes in a collection of items and returns a specific subset of those items

• eqArrays(array1, array2):

  • function that takes in 2 arrays and returns true if the arrays are equal and false otherwise

• eqObjects(object1, object2):

  • function that takes in 2 objects and return true if they are equal and false otherwise

• findKey(object, callback):

  • function that takes in an object and callback and returns the first key that meets the criteria specified in callback

• findKeyByValue(object, value):

  • function that takes in an object and a value and returns the first key that corresponds to that value

• flatten(array):

  • function that takes in an array that contains elements including nested array of elements and returns a flattened version of the array

• map(array, callback):

  • function that takes in an array and a callback and returns a new array based on the results of the callback on each item in the array

• middle(array):

  • function that takes in an array and returns middle most element of the array. If array is even, return two middle indices. If odd, returns middle index.
