🐛 Error Logs

Encountered an issue? Don't lose that knowledge!

This repo includes a dedicated error-logs/ folder to document and track errors you face during learning. This personal knowledge base helps you:

• 🔍 Debug faster when the same issue repeats
• 📖 Build a searchable reference of solved problems
• 🧠 Understand the why behind each fix

Structure

error-logs/
├── README.md                   ← How to use the error log system
├── TEMPLATE.md                 ← Copy this for every new issue
├── beginner-errors/            ← Errors during beginner topics
├── intermediate-errors/        ← Errors during intermediate topics
└── advanced-errors/            ← Errors during advanced topics

How to Log an Error

1. Copy error-logs/TEMPLATE.md
2. Rename it: YYYY-MM-DD-short-description.md
3. Place it in the relevant category folder
4. Fill in all sections (error message, what you tried, the fix, root cause)

💡 Even small errors are worth logging — they often come back!
