• function2(tail): returns the last element of an array
• function3(middle): returns the middle element of an odd-numbered array, and the two middle elements of an even-numbered array
• function4(assertEqual): checks if two strings are equal
• function5(eqArrays): checks if two arrays are equal
• function6(eqObjects): checks if two objects are equal
• function7(countLetters): returns an object with each letter from a string as keys, and the number of iterations of said letters as a value
• function8(countOnly): takes an array as a first parameter, an object as the second parameter, returns an object counting the number of times each keys from the second parameter appear in the array
• function9(findKeyByValue): finds which keys have a designated value within an object
• function10(findKey): returns first key with searched value in object
• function11(flatten): flattens nested arrays one level
• function12(letterPositions): takes a string as a parameter and returns an object with the letters within the string for keys, and the position of each iteration of the letter as a value
• function13(map): takes in an array as a parameter, returns a new array with just the first letter from each string within the first array
