• assertEqual(actual, expected): takes 2 values and returns true if equal, false otherwise.
• assertObjectsEqual(actual, expected): takes 2 objects and logs a message to assert if they are equal or not.
• countLetters(string): takes a sentence and returns the count of each of the letters in the sentence.
• countOnly(allItems, itemsToCount): takes in a collection of items and returns a count of a subset of those items.
• eqArrays(array1, array2): takes in two arrays and returns true if the arrays are equal and false otherwise.
• eqObjects(object1, object2): takes in 2 objects and returns true if they are equal and false otherwise.
• findKey(object, callback): takes an object and a callback and returns the first key that meets the criteria of the callback.
• findKeyByValue(object, value): takes in an object and value and return the key that corresponds to that value.
• flatten(array): takes in an array that can be a nested array and return a flattened array.
• head(array): takes an array and returns the first element of the array.
• letterPositions(string): takes in a string and returns the indices of the letter positions in the string.
• map(array, callback): takes in an array and a callback and returns a new array with each item modified by the callback.
• middle(array): takes in an array and returns the most middle element or elements of the array.
• tail(array): takes in an array and returns all elements of the array except the first.
