Documentation

The following functions are currently implemented:

assertArraysEqual(arrayOne, arrayTwo): comparing two arrays and returning an appropriate message(Passed or Failed) if they match or not.
assertEqual(actual, expected): compareing the two values it takes in and returning a message telling us if they match or not.
assertObjectsEqual(actual, expected): taking in two objects and printing out an appropriate message to the console if it passed or failed.
countLetters(str): taking in a sentence (as a string) and then returning a count of each of the letters in that sentence.
countOnly(allItems, itemsToCount): taking in a collection of items and returning counts for a specific subset of those items.
eqArrays(first, second): taking in two arrays and returning true or false, based on a perfect match.
eqObjects(object1, object2): taking in two objects and returning true or false, based on a perfect match.
findKey(object, callback): takeing in an object and a callback and returning the first key for which the callback returns a truthy value.
findKeyByValue(object, value): takeing in an object and a value and returning the first key which contains the given value. If no key of given value found then returning undefined.
flatten(array): taking in an array containing elements including nested arrays of elements, and returning a "flattened" version of the array.
head(array): returning the first element from the array.
letterPositions(sentence): returning all the indices (zero-based positions) in the string where each character is found.
map(array, callback): returning a new array based on the results of the callback function.
middle(array): taking in an array and returning the middle-most element(s) of the given array.
tail(array): returning everything except for the first item (head) of the provided array.
takeUntil(array, callback): collecting items from a provided array until the callback provided returns a truthy value and returning a slice of the array with elements taken from the beginning.
without(source, itemsToRemove): returning a subset of a given array, removing unwanted elements.
