💡 Key Technical Challenges

The primary challenge was implementing smooth real-time preview updates without performance degradation. I solved this using a debounced rendering approach that delays the preview update until the user stops typing for 300ms, preventing excessive DOM re-renders. Additionally, managing state persistence with localStorage while handling import/export operations required careful coordination between the file system API and browser storage.

🛠️ Technologies Used

• HTML5
• CSS3
• JavaScript (Vanilla)

🎯 What I Learned
