in reply to What defines the choice of a Hash or an Array?

How do you know which one to use and when?
If you know the difference between an array and a hash, you'll know when to use which.

`perldoc perldata'

    I do know the difference, but you could use an array, as it's ordered, and, for the same thing, you could just use a hash and then sort it.

    I wanted to hear from people on their preference and I thought that there might be a performance issue etc.

    But thanks for the links.

      Say you live a city next to an airport, and you want to visit a friend who lives 20 miles away at the other end of city also next to an airport, do you fly or do you drive?

      Use a hash when it benefits you to do so, not just because you can.
