You Can Read Code You Didn't Write
When AI hands you 40 lines you didn't type, it can feel intimidating. Good news: you don't need to understand every character to review it well.
Reading code is a skill, and it's mostly about skimming for the shape and tracing the important path — not memorizing syntax.
In this lesson you'll learn a calm, repeatable way to make sense of any AI-generated code, even as a beginner.
Step 1: Read Top to Bottom, Fast
First pass: just skim. Don't analyze. Get the gist of what this file is roughly about.
Ask: what are the big chunks? Imports at the top, a function or two in the middle, maybe a call at the bottom. You're building a mental map, not solving anything yet.
Think of it like skimming a recipe before cooking — you spot 'ingredients, then steps, then serve' before you read any step closely.
import { fetchUser } from './api';
function greet(user) {
return 'Hello, ' + user.name + '!';
}
async function showGreeting(id) {
const user = await fetchUser(id);
console.log(greet(user));
}
showGreeting(42);Names Are Your Cheat Sheet
Well-named code tells you what it does without comments. In that example, fetchUser, greet, and showGreeting basically narrate the program.
Read the names like a sentence: 'fetch a user, greet a user, show the greeting.' You just understood the file's purpose without reading any logic deeply.
If AI gives you names like x, data2, or doStuff, that's a smell — ask it to rename things clearly.
Step 2: Trace the Main Path
Second pass: pick the one path that matters and follow it like a story.
'We call showGreeting(42) → it fetches user 42 → passes that user to greet → which builds a hello string → and logs it.' That's the whole journey.
You don't need to read error handling or edge cases yet. Trace the happy path first; the rest is detail.
Run It to See What It Really Does
Reading tells you what code should do. Running tells you what it actually does. Whenever you can, execute it.
Add a quick console.log to watch values flow through. Run the snippet below to see how a small log reveals the real behavior.
function total(items) {
let sum = 0;
for (const item of items) {
console.log('adding', item.price);
sum += item.price;
}
return sum;
}
console.log('TOTAL:', total([{ price: 5 }, { price: 3 }, { price: 7 }]));The Best Tool: Ask AI to Explain It
You have a tireless tutor built in. When code confuses you, ask the AI that wrote it (or any AI) to walk you through it in plain English.
Be specific about your level so it doesn't drown you in jargon. Try a prompt like this in Cursor, Claude Code, or Copilot chat.
Explain this code to me like I'm new to programming.
Go line by line in plain English.
For each line, say what it does and why it's there.
Avoid jargon, or define any term you use.
[paste the code here]Ask 'What If' Questions
Once you get the basic flow, probe it. AI is great at answering hypotheticals about the code's behavior.
These questions reveal hidden assumptions and edge cases — exactly the spots where bugs live. Examples you can paste:
About the code above, answer briefly:
- What happens if the list is empty?
- What if a user has no name?
- What if fetchUser fails or returns nothing?
- Which line would break first with bad input?Use Comments and Diffs as a Map
AI tools give you helpers for free. Use them:
- Comments: ask AI to add short comments explaining each block, then read those.
- Diffs: in Cursor and Claude Code, changes show up green (added) and red (removed) so you see exactly what's new.
- Inline chat: highlight a confusing line and ask 'what does this do?' right there.
You're never alone with a wall of code — the tools are built to narrate it.
It's Okay Not to Understand Everything
You won't grasp every line, and that's fine. Aim for 'enough to judge it', not 'expert in every detail.'
Enough means: you know what it's for, you can trace the main path, and you'd know roughly where to look if it broke. That's a solid review.
Understanding deepens naturally the more you read. Every AI snippet you trace makes the next one easier.
Read in Your Real Tools
You'll rarely read code in isolation — you'll read it inside the tool that generated it. Make the tool work for you:
- Cursor / Windsurf: highlight any block and press the chat shortcut to ask 'explain this' in context.
- Claude Code: ask it to summarize a file before you open it, so you skim with a map already in hand.
- Copilot: hover or use chat to get inline explanations of a function.
- v0 / Bolt / Lovable: read the generated component, then ask 'walk me through what this screen does.'
The tool that wrote the code is also your best guide to reading it.
Your Reading Routine
Put it together into a routine for any AI code:
- Skim top to bottom for the big chunks.
- Read the names like a sentence to get the purpose.
- Trace the main happy path step by step.
- Run it with a log or two to see real behavior.
- Ask AI to explain or answer 'what if' on anything fuzzy.
Five steps, a couple of minutes, and mystery code becomes reviewable code.
Quick Check
AI just generated a file you've never seen. You want to understand it quickly without getting stuck on every detail. What's the smart first move?
Recap: Make Sense of Any Code
What you can now do with AI-generated code:
- Skim first to map the big chunks before reading closely.
- Use clear names as a free narration of what the code does.
- Trace the happy path like a story instead of reading randomly.
- Run it with a quick log to see actual behavior.
- Ask AI to explain line by line and answer 'what if' questions.
You don't need to understand every character — just enough to judge it. Next: spotting the bugs and bad patterns hiding inside.
