How to Use GitHub Copilot for JavaScript Projects in 30 Minutes

If you're a solo founder or indie hacker, you know that time is your most precious resource. The last thing you want is to get bogged down in writing boilerplate code or searching for syntax details. That's where GitHub Copilot comes in. In this guide, I'll show you how to leverage GitHub Copilot for your JavaScript projects in just 30 minutes.

Prerequisites

Before we dive in, here’s what you’ll need to get started:

1. GitHub Account: You need a GitHub account to access Copilot.
2. Visual Studio Code (VS Code): Download and install VS Code.
3. GitHub Copilot Subscription: As of March 2026, GitHub Copilot costs $10/month, with a free trial available for new users.

Step-by-Step Setup

Step 1: Install GitHub Copilot

1. Open VS Code.
2. Go to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side or pressing Ctrl+Shift+X.
3. Search for "GitHub Copilot" and click on "Install."
4. After installation, sign in with your GitHub account when prompted.

Expected Output: You should see a Copilot icon in the bottom right corner of VS Code, indicating it's active.

Step 2: Create a New JavaScript File

1. Create a new folder for your project and open it in VS Code.
2. Inside the folder, create a new file named app.js.

Step 3: Start Coding with Copilot

1. Begin typing a JavaScript function. For example, type function add(a, b) { and then press Enter.
2. Copilot will suggest code for you. Accept the suggestion by pressing Tab.

Expected Output: You should see a complete function definition for adding two numbers.

Step 4: Generate More Complex Code

1. Try typing a comment describing what you want to achieve, like // Create a function that fetches data from an API.
2. Press Enter, and Copilot will generate a function for you.

Expected Output: You'll get a fully functional JavaScript fetch call wrapped in a function.

Step 5: Testing Your Code

1. To run your JavaScript code, open the terminal in VS Code (`Ctrl + ``).
2. Type node app.js and hit Enter to execute your script.

Expected Output: You should see the results of your code in the terminal.

Troubleshooting Common Issues

• Copilot Not Suggesting Code: Make sure you're connected to the internet and that you've signed in to your GitHub account.
• Suggestions Not Relevant: If you find the suggestions aren’t useful, try providing more context in your comments.

What’s Next?

Once you've got the hang of using Copilot, consider exploring more advanced features:

• Refactoring: Ask Copilot to refactor your code for better performance.
• Integrating with Other Tools: Consider using Copilot in conjunction with testing frameworks like Jest for better code coverage.

Conclusion

In just 30 minutes, you can set up GitHub Copilot and start writing JavaScript code more efficiently. This tool can save you time and help you focus on building your product instead of getting lost in syntax.

What We Actually Use

We use GitHub Copilot for quick prototyping and to generate boilerplate code. While it’s not perfect and sometimes makes suggestions that don’t fit our needs, it has greatly accelerated our development process, especially for repetitive tasks.

If you're ready to boost your coding efficiency, give GitHub Copilot a try.
