Given a string, return true if its length is even or false if the length is odd.
oddOrEven("apples") ➞ true
// The word "apples" has 6 characters.
// 6 is an even number, so the program outputs true.
oddOrEven("pears") ➞ false
// "pears" has 5 letters, and 5 is odd.
// Therefore the program outputs false.
oddOrEven("cherry") ➞ true
