Documentation

The following functions are currently implemented:

• head : Returns the first item in the array
• tail: Returns the "tail" of an array: everything except for the first item (head) of the provided array.
• middle: Take in an array and return the middle-most element(s) of the given array.
• assertArraysEqual: Take in two arrays and console.log an appropriate message to the console.
• assertEqual: Compare the two values it takes in and print out a message telling us if they match or not.
• assertObjectsEqual: Will take in two objects and console.log an appropriate message to the console.
• countLetters: Take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly: Will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• eqArrays: Takes in two arrays and returns true or false, based on a perfect match.
• eqObjects: Will take in two objects and returns true or false, based on a perfect match.
• findKey: Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• findKeyByValue: Takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• letterPositions: Return all the indices (zero-based positions) in the string where each character is found.
• map: The map function will take in two arguments: An array to map and a callback function. It will return a new array based on the results of the callback function
• takeUntil: Will keep collecting items from a provided array until the callback provided returns a truthy value.
• without: Return a subset of a given array, removing unwanted elements
