Documentation

The following functions are currently implemented:

• function assertArraysEqual(arr1, arr2): takes in two arrays and console.log an appropriate message to the console.
• function assertEqual(actual, expected): prints out a pass or fail message based on if actual value matches expected value
• function AssertObjectsEqual(actual, expected): take in two objects and prints an appropriate pass/fail message to the console
• function countLetters(string): takes in a string and then return a count of each of the letters in that sentence
• function countOnly(allItems, itemsToCount): returns true or false if the names or values provided are already in the object
• function eqArrays(first, second): takes in two arrays and returns true or false, based on a perfect match
• function eqObjects(object1, object2): returns true if both objects have identical keys with identical values, otherwise returns false
• function findKey(object, callback): scans object and returns the first key for which the callback returns a truthy value
• function findKeyByValue(object, value): takes in an object and a value. Scans the object and returns the first key which contains the given value. If no key with that given value is found, function returns undefined
• function head(array): returns the first item in the array
• function letterPosition(sentence): returns all the indices (zero-based positions) in the string where each character is found
• function map(array, callback): takes in two arguments - an array to map, and a callback funtion - function returns a new array based on the results of the callback function
• function middle(array): takes in an array and return the middle-most element(s) of the given array
• function tail(array): returns everything except for the first item of the provided array
• function takeUntil(array, callback): keeps collecting items from the input array until the callback provided returns a truthy value
• function without(source, itemsToRemove): takes in a source array and itemsToRemove array, and will return a subset of a given array, removing unwanted elements
