Abstraction: Daily LeetCode practice builds professional software engineering skills beyond interviews
Key points:
- Author (front-end engineer) completed 400+ LeetCode problems over one year as a non-interview professional development habit
- Key benefits: automatic edge-case thinking, ~50% faster problem-solving speed after 6 months, reduced fear of complex tasks
- Mastering one topic deeply before moving on (easy → medium → hard within a domain) accelerates pattern recognition
- Posting solutions and writing clear explanations transfers to workplace communication and code quality
- Daily 30-minute consistent habit more effective than sporadic intensive sessions; tracking streaks builds accountability
- JavaScript-specific: regular practice deepens language fluency (e.g., knowing exactly what .slice() vs .splice() does)
