• assertEqual(actual, expected): Checks that a value is strictly equal to an expected value.
• assertObjectsEqual(actual, expected): Checks that two objects are equal.
• countLetters(string): Returns a count of all letters from a string.
• countOnly(array, object): Takes in a collection of items and returns a count for a specified subset of items.
• eqArrays(actual, expected): Checks that two arrays equal by comparing each element.
• eqObjects(object1, object2): Checks that two objects are equal by comparing key-value pairs.
• findKey(object, callback): Returns the key belonging to the object when the callback is true.
• findKeyByValue(object, value): Returns the key of an object by its value.
• fatten(array): Returns a flattened version of a nested array. Original array is preserved.
• head(array): Returns the first value of an array. Original array is preserved.
• letterPositions(string): Returns the indices corresponding to each letter in a string.
• map(array, callback): Returns a transformed array as specified by the callback.
