Theres an art and a science to transforming unmaintainable code into elegant simplicity. It takes practice, experimentation, and deep thought.
become fluent in a new language
One moment you feel like youre getting it. The next moment youre stuck.
Exercism provides countless small wins. The exercises are achievable mini-quests: small and well-defined, and with enough complexity to uncover bite-sized knowledge gaps.
Your solutions are the starting point for a conversation centered around style, idioms, and best practices. You can write FORTRAN in any language, as the saying famously goes, but with enough feedback, youll quickly find yourself writing the language the way it wants to be written.
Exercisms tiny toy problems, in the form of automated tests, provide a balance of constraints and freedom. The exercises encourage you to explore trade-offs and best-practices.
For code newbies and experienced programmers.
Theres a gap when youre past the basics but real-world problems leave you swamped by details and wandering down rabbit holes. Exercism aims to fill that gap with lots of small, self-contained practice problems with just enough complexity to stretch your mind around new concepts.
Each solution you write is an occasion to ponder readability and code smells. Each solution you review challenges you to articulate your experiences and gut feelings. Each discussion is an opportunity to strengthen your instincts for clean, well-factored code.
Learning a new language can be both thrilling and deeply uncomfortable.
Youre used to being productive. Now you feel hamstrung with one hand tied behind your back and an unfair suspicion that you should already know this.
You know what its like to be fluent. Suddenly youre feeling incompetent and clumsy.
Haphazard, convoluted code is infuriating, not to mention costly. That slapdash explosion of complexity is an expensive yak shave waiting to happen.
Exercism is many things: An experiment. A bunch of interesting people. Chaotic. An open source project.
Download and solve practice problems inover 30 different languages.
The solutions you write provide reviewers with clues about what you havent grasped yet. The feedback you receive will guide you to relevant study topics and dramatically increase the ease with which you write code.

Learning to program is exhilarating and challenging… and also frustrating, exhausting, and overwhelming.
