Documentation

The following functions are currently implemented:

• assertArraysEqual(arrA, arrB): Tests if the two arrays are equal
• assertEqual(actual, expected): Tests the equivalence of two given primitive data types
• assertObjectsEqual(actual, expected): Tests if the two objects are equal
• countLetters(sentence): Returns a count of each letter occur in a given string
• countOnly(allItems, itemsToCount): Takes in an array of items and returns counts for specific items
• eqArrays(arrA, arrB): Compare two arrays and return boolean
• eqObjects(object1, object2): Compare two objects to find out if both objects have identical keys with identical values
• findKey(object, callback): Return the first key of a given object that the callback function returns a truthy value
• findKeyByValue(object, value): Return a key the match the given value
• head(arr): Return the first element of the given array
• letterPositions(string): Return index position(s) of each letter in the given sentence
• map(array, callback): Take in an array of string and a callback function and return an array of the first letter of each word
• middle(arr): Find and return the middle character(s) of an array based on the length of the array (return 1 character if odd and return 2 characters if even)
• tail(arr): Return a new array of element from index 1 to the rest.
