Learn to read error messages like a senior developer and use AI to diagnose and fix bugs across the frontend, backend, and database layers.
Before
Find an error in one of your projects (or intentionally create one by passing `undefined` to a `.map()` call). Read the stack trace — identify the file, line, and what is undefined. Then write a debugging prompt for AI that includes the error message, the code, and what you expected. Compare AI's diagnosis with your own.
After
The difference between a junior and senior developer is not that seniors do not get errors — it is that they read the error message first. A stack trace tells you exactly what went wrong and where. AI amplifies this: give it the error, the relevant code, and what you expected, and it will pinpoint the root cause.
Tip
Be specific about what you need. The more context you provide, the better the result.
