Well, we've looked at CI pretty thoroughly, and we hope all we have been through helps you in your day-to-day programming. We've also developed some of our code in the process. When you must have gone through some of the code in this book, you must have thought "I could write that better…". Everyone has their own style, and CI gives you a lot of freedom.
The CI community is full of people who write good code and luckily many of them make it available free of cost to the rest of us. So there's a lot of code out there that may save you a lot of work. For example, if you want to create dynamic graphs of data drawn from your database—you can sit down and write the code yourself or search for a ready-made solution.
Using third-party code in our applications and websites is something quite usual, because we can't develop everything, it wouldn't be productive. Luckily for us CI's Wiki is very extensive and has a lot of libraries that we can use.
