  • assertArraysEqual(array1, array2): A function takes in two arrays and print an appropriate message to console
  • assertEqual(actual, expected): A function compares two values and print out a message telling users if they match or not
  • assertObjectEqual(object1, object2): A function takes in two objects and print an appropriate message to the console
  • countLetter(strToCheck): A function counts how many times letters appear
  • countOnly(allItems, itemsToCount): A function only returns if the itemsToCount appears and how many times it appears
  • eqArrays(array1, array2) : A function takes in two arrays and returns true or false, based on a perfect match
  • eqObjects(object1, object2): A function takes in two objects and returns true or false, based on a pefect match
  • findKey(keyList, callback): A function takes in an object and a callback, scan through the object and return the first key where the callback returns true. If no key found, return undefined
  • findKeyByValue(object, searchValue): A function help searching for a key on an ojects where its value matches a given value
  • flatten(array): A function flatten the given array into single-level array
  • head(array): A function returns the item in the array
  • letterPositions(sentence): A function reutrns all the indices(zero-based positions) in the string where each character is found

  • tail(array): A function returns back the given array expect the first item
