Documentation

The following functions are currently implemented:

• head(array): Returns the first element of an array.
• tail(array): Returns everything but the first element of an array.
• middle(array): Returns the middle value of an array and if the array is even it returns both middle values in a new array.
• assertArraysEqual(actual, expected): Compares the result of two arrays being compared to an expected value picked by the tester.
• assertEqual(actual, expected): Strictly compares the result of two values being compared to an expected value picked by the tester.
• countLetters(string): Counts the amount of letters in an array and returns an object made of the count of each letter.
• findKeyByValue(key): Finds the desired key in an object and returns it.
• letterPositions(sentence): Takes a string and returns an object with each key being a letter and the index number in which it appears.
• countOnly(allItems, itemsToCount): This function should take in a collection of items and return counts for a specific subset of those items.
• assertObjectsEqual(actual, expected): Compares the result of two objects being compared to an expected value picked by the tester.
• eqArrays(actual, expected): Compares two arrays, if they are the same it returns true, if not false.
• eqObjects(actual, expected): Compares two objects, if they are the same it returns true, if not false.
• takeUntil(array, callback): Takes in an array and a callback function, loops through the array until the callback function requirement is met and returns the new array with every element looped through so far.
• without(array, value): Takes in an array and a value, it will remove the value given from the array and return a new array.
