Learn Coding & Build Apps

From fixing bugs to shipping small apps — AI as a pair programmer

Task

Have AI explain an error and propose a minimal fix

Time

~15 min

Suggested tool: DeepSeek

How this scenario works

Coding AIs explain errors, complete code, and break down tasks. You still run tests, understand changes, and never paste secrets. Beginners: start with “explain this code”.

Get started in minutes

1Paste the full error + related code — explain first, then fix
2Use an IDE assistant while you code
3Ask for a minimal runnable example and run it yourself
4Later: automate repeats with agents/skills

Copy-ready prompts

Explain an error

You are a senior engineer. First explain this error in plain language, then propose a minimal fix — do not rewrite the whole file.

Error:
TypeError: Cannot read properties of undefined (reading 'map')
Code:
const items = data.list;
return items.map(...)
