Programming mastery requires consistency, curiosity, and hands-on problem-solving. The “100 Days of Code” challenge is designed to help programmers at all levels develop habits that lead to tangible improvement. The goal is simple: code daily for 100 days and document progress.
Why 100 Days of Code Works
- Builds Discipline: Consistent practice improves problem-solving and coding fluency.
- Encourages Accountability: Sharing progress publicly keeps you motivated.
- Strengthens Skills: Repetition helps internalize concepts.
This roadmap provides a structured approach to help you succeed.
