Documentation

The following functions are currently implemented:

• function head(..): A function that returns the first element from the array.
• function tail(..): A function that returns every element except the head (first element) of the array.
• function middle(..): A function that returns an array with only the middle element(s) of the provided array.
• function without(..): A function that returns a subset of a given array, removing unwanted elements.
• function countOnly(..): A function that will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• function countLetters(..): A function that takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• function letterPositions(..): A function that returns all the indices (zero-based positions) in the string where each character is found.
• function findKeyByValue(..): A function that 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.
• function eqObjects(..): A function that takes in two objects and returns true or false, based on a perfect match.
• function assertObjectsEqual(..): A function that takes in two objects and console.log an appropriate message to the console.
• function map(..): A function that takes in two arguments and returns a new array based on the results of the callback function.
• function takeUntil(..): A function that takes two parameters and return a slice of the array with elements taken from the beginning. It should keep going until the callback/predicate returns a truthy value.
• function findKey(..): A function that 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.
