A linter’s tiny warning can prevent hours of debugging and teach best practices in seconds. When errors surface immediately, you connect cause and effect while the context is fresh. Interactive environments turn every small mistake into a micro-lesson that compounds into confident competence.
Instant Feedback, Instant Growth
Autograding tests transform vague objectives into concrete, verifiable progress. Write a function, see failing assertions, adjust logic, and celebrate green checks. This rapid cycle of attempt and feedback turns complex programming patterns into familiar rhythms you can reproduce on new problems with less hesitation.
