There's More Perl to Write!

• You can get both keys and values with the each function.

($key, $value) = each(%hash)
• This returns the next key and value pair.  Ideal for a loop.
• What type of loop do we use when we want something to execute while a condition is true?


while(($name, $age) = each(%studentData)) {
    print "$name is $age years old.";
}
 

• That's it!
