Top ChatGPT Prompts for JavaScript

Welcome fellow developers! As AI assistants like ChatGPT become more advanced, they can be extremely useful for automating tedious coding tasks. In this post, I’ll showcase some of my favorite prompts for JavaScript development that have helped me work more efficiently.

Code Generation

One of the most useful applications of ChatGPT is generating boilerplate code from simple descriptions. This saves a ton of time compared to writing everything from scratch.

Here’s an example prompt:

Act as a JavaScript developer. Write the skeleton code for a React component called Profile that fetches user data from an API and displays the user's name, avatar, and bio. Use async/await and proper error handling.

And here is the code ChatGPT generated:

import React, { useState, useEffect } from 'react';

const Profile = () => {
  const [user, setUser] = useState(null);
  const [error, setError] = useState(null);

  useEffect(() => {
    const fetchUser = async () => {
      try {
        const response = await fetch('/api/user');
        const data = await response.json();
      } catch (err) {

  }, []);

  if (error) {
    return <p>Error fetching user!</p>;

  if (!user) {
    return <p>Loading...</p>;

  return (
      <img src={user.avatar} alt="avatar" />

export default Profile;

This saves me a bunch of typing and sets up all the hooks and state management!


ChatGPT also makes debugging code so much easier. I can just describe the bug and it will analyze the code and suggest fixes.

This React component throws an error when clicking the button. Please analyze the code and explain the bug. Also provide the fixed code.

// Component code here with bug

It’s like having an expert developer over your shoulder!

Code Reviews

Similarly, I can paste in code snippets and ask ChatGPT to review them for best practices, optimizations, and improvements.

Please review this React component code and provide constructive feedback for improvements following best practices. Point out any issues and provide suggestions.

// Component code here 

This allows me to improve my code even if I don’t fully understand why something may be problematic.

Explain Concepts

As a lifelong learner, I’m always trying to strengthen my conceptual knowledge. ChatGPT is great for explaining complex JavaScript topics through examples.

Explain the factory pattern in JavaScript including a code example implementing the pattern.

It breaks down the concepts very clearly, often better than technical documentation!

Helpful Prompts to Try

Here are a few more handy prompts for JavaScript developers:

  • Refactor this component to use React hooks instead of classes
  • Suggest improvements for this fetch API call
  • Explain event delegation in JavaScript
  • Fix the infinite loop in this code
  • Compare pros and cons of React vs Vue

Formatting Tips

To get the most out of ChatGPT for coding, make sure to:

  • Delimit code blocks with triple backticks
  • Specify you want JavaScript code
  • Use clear, direct instructions and descriptions
  • Provide examples when possible

Start Automating Your Work

I hope these prompts spark some ideas for how you can integrate ChatGPT into your workflow! It has made JavaScript development so much more enjoyable for me by eliminating grunt work. Let me know what prompts have been most useful for you. And happy coding!
