Throughout this book, we demonstrate concepts through interactive Ruby sessions. Strings are a good place to start because not only are they a useful data type, they’re easy to create and use.

Only if you’re on the very cutting edge should you have to come up with your own algorithms. If you’re lucky, the same is true for data. Some applications are driven entirely by the data the users type in. Sometimes data just comes to you naturally: if you’re analyzing spam, you should have no problem getting all you need. You can download a few public data sets—word lists, geographical data, lists of prime numbers, public domain texts —as though they were third-party libraries. But if you need some other kind of data, it doesn’t look good. Where’s the data going to come from? More and
