Reading AI Code Well Enough to Modify It

You don’t have to write code from scratch, but you do need to read what the AI hands you. Here are the reading skills that matter.

Reading Is the Real Skill

You can vibe-code forever without writing code, but you will hit a ceiling if you cannot read what the AI produces. The good news: reading is ten times easier than writing, and you already do it every time you skim an email.

The file name — tells you the job (login/page.tsx = login page)
The function name — tells you the action (sendWelcome = sends an email)
The inputs in parentheses — what goes in
The return — what comes out
The words in the middle — rough story of what happens

// Example: an AI-generated function you might see

export async function sendWelcome(email: string, name: string) {
  const subject = `Welcome to PupLoop, ${name}!`;
  const body = `Hi ${name}, we're excited to have you.`;

  try {
    await resend.emails.send({
      from: "team@pupfoo.com",
      to: email,
      subject,
      html: body,
    });
  } catch (err) {
    console.error("welcome email failed", err);
  }
}Read it like a paragraph. This is a function called sendWelcome that takes an email and a name, writes a subject, writes a body, and tries to send an email.

async, await — just means wait for this
import — getting something from another file
export — making something usable elsewhere
interface, type — defining a shape like a form template
useEffect, useState — React's words for state and reactions

Each day, open one file in your app and explain it out loud. Then ask your AI to grade your explanation. Two weeks of this and you will read most small files fluently.

The big idea: reading beats writing. Ten minutes a day reading your own AI-generated code turns you from a prompter into a maker — even if you never write a line yourself.

In a well-organized code project, what does the file name typically indicate?
1. The date when the file was last modified
2. The programming language used to write it
3. The name of the developer who created it
4. The purpose or job that the file performs
When you see a function named 'sendWelcome', what is its most likely purpose?
1. To store welcome message data in a database
2. To send a welcome email or message
3. To validate user login credentials
4. To display a welcome screen to the user
What do the values listed inside the parentheses after a function name represent?
1. The inputs or data the function needs to work with
2. The file paths where the function is stored
3. The outputs the function will produce
4. The programming language the function uses
What does the 'return' statement in a function specify?
1. The location where the function is defined
2. The order in which the function runs
3. The programming language being used
4. The data or result that the function sends back after working
What does the 'async' keyword indicate about a function?
1. The function will run automatically when the page loads
2. The function will wait for asynchronous operations to complete
3. The function will execute slowly by design
4. The function cannot be called by other functions
What is the purpose of the 'import' statement in code?
1. To display content on a webpage
2. To create a new variable in memory
3. To include code from another file in your current file
4. To send data to an external server
What does it mean to 'export' something from a code file?
1. To send data to a browser
2. To remove formatting from the data
3. To make code available for use in other files
4. To delete the code from the project
What is the purpose of an 'interface' or 'type' in programming?
1. To define the visual styling of elements
2. To control how fast code executes
3. To connect to external databases
4. To describe the shape or structure that data should have
In React, what does 'useState' represent?
1. A function that fetches data from an API
2. A way to style HTML elements
3. A hook for managing changing data within a component
4. A method for routing between pages
In React, what is the purpose of 'useEffect'?
1. To create animations on the page
2. To define the visual layout of a page
3. To perform side effects like fetching data when conditions change
4. To validate form inputs
Why does the lesson recommend reading your own AI-generated code daily?
1. To find bugs that the AI made
2. To gradually build fluency in understanding code structure
3. To reduce the amount of code you need to write
4. To memorize the exact syntax for exams
When should you slow down and read every line of AI-generated code with extra care?
1. When the code has many comments
2. When the code uses a new programming language
3. When the code handles payments, authentication, or anything touching money
4. When the code is for a hobby project
What does the 'await' keyword do when used inside an async function?
1. It pauses execution until the promised operation completes
2. It repeats the function multiple times
3. It makes the function run faster
4. It automatically saves the function to a file
What is the recommended technique for checking if your understanding of a code file is correct?
1. Memorizing all the variable names
2. Writing a new function based on the file
3. Reading the file three times in a row
4. Explaining the file out loud and asking an AI to evaluate your explanation
What does the term 'props' refer to in React development?
1. CSS styles applied to elements
2. State stored in a global database
3. Data passed from a parent component to a child component
4. A testing framework for React applications
