: takes in two arrays and console.logs a message if they are a perfect match or not -
assertEqual
: compares two values and prints out a message telling us if they match or not -
assertObjectsEqual
: takes in two objects and console.logs a message to the console if they are a perfect match or not -
countLetters
: takes in a sentence (as a string) and then returns a count of each of the letters in that sentence -
countOnly
: takes in a collection of items and returns counts for a specific subset of those items -
eqArrays
: takes in two arrays and returns true or false, based on a perfect match -
eqObjects
: takes in two objects and returns true or false, based on a perfect match -
findKey
: takes in an object and a callback and returns the first key for which the callback returns a truthy value, If no key is found, then it returns undefined -
findKeyByValue
: takes in an object and a value and returns the first key which contains the given value If no key with that given value is found then returns undefined -
flatten
: takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array -
