Ranked in these QuestionsQuestion Ranking
Pro Human review and feedback
Pro Practice with production tools
Unlike many code practice websites, Exercism requires the user to develop and test entirely offline, submitting only the finished code. This promotes familiarity with essential tools and workflow, not just the bare language.
Pro Finds practical examples for advanced abstract concepts
Clearly explains concepts through interesting and hands on examples.
Con Custom commandline client
Exercism requires using a CLI utility to fetch and submit exercises. This is inconvenient compared to web-only alternatives, and poses an additional barrier to entry for some users.
Con Some parts of the book feel rushed
Grammar errors and poorly explained ideas can be found throughout the book.
Con Some previous knowledge in Java or C# is recommended
Not a book for beginners to programming.
