Field notes

The homepage lays out 18 ordered topic worlds, from arrays and hashing to bit manipulation, and says each guide can show an algorithm running on user-supplied input. Its practice formats also include pattern-identification quizzes and timed, company-tagged problem sets. A separate codebase-round format is described as using a real repository for a bug, a feature, and a performance task.
