Introduction
Reading code written by someone else—or code you wrote six months ago—can feel like deciphering a foreign language. Instead of staring at it for 30 minutes, you can paste it into ChatGPT and ask for a clear, beginner-friendly explanation.
Here is how to use AI effectively as a learning tool for understanding code.
Step 1: Use the "Explain Like I Am 5" Technique
The key to getting a good explanation is telling the AI your current knowledge level.
Try this Prompt:
I am a beginner learning JavaScript. Explain the following code to me like I am 5 years old. Do not use jargon unless you explain it immediately after. Tell me what each line does and why it is needed.

Step 2: Ask for a Visual Walkthrough
For complex logic or loops, a step-by-step walkthrough helps more than a summary.
Try this Prompt:
Walk me through this function step by step. Pretend I am running it in my head. For each iteration of the loop, tell me what the value of each variable is. Use a table format if it helps.

Step 3: Translate Code Between Languages
If you know one language but need to understand code written in another, AI can translate the logic.
Try this Prompt:
I know Python well but I am new to TypeScript. Translate this TypeScript code into Python so I can understand the logic. Then explain the key TypeScript-specific concepts (like types or interfaces) that the original code uses.

FAQ
Is it safe to paste proprietary code into ChatGPT?
No. Avoid pasting proprietary or sensitive code into public AI tools. Use a local AI tool like Ollama or GitHub Copilot's Chat (which offers IP indemnity) for work code.
Will AI always explain the code correctly?
Not always. AI can misinterpret complex logic, especially with edge cases. Always verify the explanation by tracing through the code yourself.
