Documentation

The following functions are currently implemented:

• function head: retrieve the head/first element from the array
• function tail: retrieve tail that is meant to be every element except the head (first element) of the array.
• function middle: take in an array and return the middle-most element(s) of the given array.
• function assertArraysEqual: take in two arrays and console.log an appropriate message to the console.
• function assertEqual: compare the two values it takes in and print out a message telling us if they match or not.
• function assertObjectsEqual: take in two objects and console.log an appropriate message to the console.
• function countLetters: take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• function countOnly: When given an array and an object, it will return an object containing counts of everything that the input object listed.
• function eqArrays: takes in two arrays and returns true or false, based on a perfect match.
• function eqObjects: take in two objects and returns true or false, based on a perfect match.
• function findKey: takes in an object and a callback. scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it return undefined.
• function findKeyByValue: takes in an object and a value, scan the object and return the first key which contains the given value. If no key with that given value is found, then it return undefined.
• function letterPositions: return all the indices (zero-based positions) in the string where each character is found.
• function map: take in two arguments: 1) An array to map, 2)A callback function. and return a new array based on the results of the callback function.
• function takeUntil: take in two parameters: 1) The array to work with, 2) The callback. and return a "slice of the array with elements taken from the beginning." It keep going until the callback/predicate returns a truthy value.
• function without: return a subset of a given array, removing unwanted elements.
