Functions lab

Instructions: with your partner, take 5 minutes to review these exercises, and make a list of things you don't understand that we still need to review to get the exercises completed, and we'll go over them.

1. Define a function maxOfTwoNumbers that takes two numbers as arguments and returns the largest of them. Use the if-then-else construct available in Javascript. You'll have to remember your pre-work, or do some googling to figure this out.
2. Define a function maxOfThree that takes three numbers as arguments and returns the largest of them.
3. Write a function that takes a character (i.e. a string of length 1) and returns true if it is a vowel, false otherwise.
4. Define a function sumArray and a function multiplyArray that sums and multiplies (respectively) all the numbers in an array of numbers. For example, sumArray([1,2,3,4]) should return 10, and multiplyArray([1,2,3,4]) should return 24.

5. Define a function reverseString that computes the reversal of a string. For example, reverseString("jag testar") should return the string "ratset gaj".
6. Write a function findLongestWord that takes an array of words and returns the length of the longest one.
7. Write a function filterLongWords that takes an array of words and an number i and returns the array of words that are longer than i.
