• tail(arr): Return all item in except the head of a given array
• middle: Return the middle-most item of a given array
• assertArraysEqual(firstArr, secArr): Write message to console if assertion (array) pass or fail
• assertEqual(actual, expected): Write message to console if assertion (primitive type) pass or fail
• assertObjectsEqualfunction(object1, object2): Write message to console if assertion (Object) pass or fail
• countLetters(str): Count occurance of each letter in a given string
• countOnly(allItems, itemsToCount): Given a list of item, return counts for a specific subset of those items
• eqArrays(arr1, arr2): Compare two arrays, return true if equal else false
• eqObjects(object1, object2): Compare two objects, return true if equal, else false
• findKey(object, callback): Scan given object and return the first key for which the callback returns a truthy value. Return undefined if no key is found
• findKeyByValue(object, value): Given an object, return the first key which contains the given value, return undefined if not found
• flatten(arr): Flatten nested arrays

• map(array, callback): Take in an array and a callback function,return a new array based on the results of the callback function
• takeUntil(array, callback): Return a slice of the array, with elements taken from the beginning, until callback condition meets
