Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Take in two arrays and console.log an appropriate message to the console.
• assertEqual(actual, expected): Compare the two values it takes in and print out a message telling us if they match or not.
• assertObjectsEqual(actual, expected): Take in two objects and console.log an appropriate message to the console.
• countLetters(str): Return a count of each of the letters in that sentence.
• countOnly(allItems, itemsToCount): Take in a collection of items and return counts for a specific subset of those items.
• eqArrays(array1, array2): Takes in two arrays and returns true or false, based on a perfect match.
• eqObject(object1, object2): Take in two objects and returns true or false, based on a perfect match.
• findKey(object, callback): Return the first key for which the callback returns a truthy value.
• findKeyByValue(object, key): Return the first key which contains the given value.
• flatten(array): Return a "flattened" version of the array.
• head(array, str): Returns the first item in the array.
• letterPositions(sentence): Return all the indices (zero-based positions) in the string where each character is found.
• map(array): Creates a new array populated with the results of calling a provided function on every element in the calling array.
• middle(array): Return the middle-most element(s) of the given array.
• tail(array): Returns everything except for the first item of the provided array.
