JavaScript examples of functions that you could be asked to write

1. Return the maximum of three numbers. For example:

             var max =  max_of_three(2, 30, -5)
             // The value of max would be 30

2. Reverse the items in an array or list. For example:

             var a1 = [1, 2, 3, 4, 5];
             var a2 = reverse(a1):
             // The value of a2 would be [5, 4, 3, 2, 1]. And
             var a3 = reverse(a2);  // has the value [1, 2, 3, 4, 5]

3. Find the maximum number a list of numbers.
4. Find the length of each string a in list with different types of items.
5. Find the sum of the numbers in a list, where the list could contain both numbers and non-numbers. For example in the list [1, “a”, “b, 2, true, 3] the sum of the numbers is 6.
6. Given a list of arbitrary items. Count the number of strings or numbers or Booleans the list contains. There are many criteria that could be used for counting: how many are negative numbers; how many numbers are bigger than 100; how many strings contain the letter ‘A’ and are of length less than 5.
7. Given two lists of numbers, do the lists have the same numbers in the same order?

             // r1 is true.
             var r1 = same_numbers( [1, 2, 3, 4, 5], [1, 2, 3, 4, 5])
             // r2 is false.
             var r2 = same_numbers([1, 2 ,3, 4, 5], [1, 2, 3, 5, 4])
