4. Introduction to the exercises

All of the exercises are under the /exercises directory: http://localhost:9000/exercises/. You can load them in the browser like this: http://localhost:9000/exercises/name, for example http://localhost:9000/exercises/ex01/

You can write your answers in that directory. We’ve tried to make the exercises build on each other, so you get a sense of progressive enhancement.

If you ever fall behind, or decide you don’t like your solution, you can “cheat” and look at ours under the /answers directory.

(There are almost always multiple ways to solve a problem; ours is not “the right” way, it’s just the way that we thought was easiest/best/simplest.)
