Replit Common Mistakes to Avoid
Mistake #1: Hardcoding secrets
❌ Faux : Pasting API keys straight into your code where anyone can see them.
✅ À droite : Store every key in the Secrets tab as environment variables.
Mistake #2: Vague AI prompts

✅ À droite : Write a clear prompt, like a web app showing an interactive map.
Mistake #3: Skipping version control
❌ Faux : Editing big projects with no backup of older versions.
✅ À droite : Se connecter à GitHub tôt so you can fix issues by rolling back.
