How to Use GitHub Copilot to Write Your First 10 Lines of Code in 30 Minutes

If you’re a beginner looking to dip your toes into coding, GitHub Copilot could be a game-changer for you. But let’s be honest: diving into coding can feel overwhelming, especially when you’re staring at a blank screen. The good news? You can write your first 10 lines of code in just 30 minutes using Copilot, and I’m here to walk you through it.

Prerequisites: What You Need to Get Started

Before you start, make sure you have the following:

1. A GitHub Account: If you don’t have one yet, sign up for free at GitHub.
2. Visual Studio Code (VS Code): Download and install it from here.
3. GitHub Copilot Subscription: It costs $10/month after a 60-day free trial. You can sign up directly in VS Code after installation.

Step 1: Set Up Your Environment (5 Minutes)

1. Open Visual Studio Code.

2. Install the GitHub Copilot Extension:

   • Go to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side of the window.
   • Search for "GitHub Copilot" and click "Install."

3. Log into GitHub:

   • After installation, you’ll need to log in to your GitHub account through the extension.

Step 2: Create a New File (5 Minutes)

1. Create a New File:

   • Click on File > New File or press Ctrl + N.
   • Save the file with a .js extension (e.g., hello.js).

2. Start Typing:

   • Begin by typing a simple comment like // This program prints "Hello, World!". Copilot will automatically suggest code based on your comment.

Step 3: Let Copilot Do Its Magic (10 Minutes)

1. Type Your Intent:

   • After the comment, type console.log( and let Copilot fill in the rest. You should see suggestions pop up. Hit Tab to accept the suggestion.

2. Write Additional Lines:

   • To create a simple program, you can type:

     // This program adds two numbers
     const a = 5;
     const b = 10;
     console.log(a + b);
     

3. Review and Modify:

   • Make sure to review the generated code. You can modify it to fit your needs or preferences. Copilot is great, but it's not perfect.

Expected Output

After following the steps, your hello.js file should look something like this:

// This program prints "Hello, World!"
console.log("Hello, World!");

// This program adds two numbers
const a = 5;
const b = 10;
console.log(a + b);

Troubleshooting: What Could Go Wrong

• No Suggestions: If you don’t see any suggestions from Copilot, make sure the extension is properly installed and you are connected to the internet.
• Inaccurate Code: Sometimes, Copilot may generate code that doesn't work as expected. Always run your code to check for errors.

What’s Next?

Once you’ve successfully written your first 10 lines of code, consider the following steps:

1. Experiment: Modify the numbers or add more console logs to get familiar with coding concepts.
2. Learn More: Check out online resources or courses on JavaScript to expand your knowledge.
3. Join Communities: Engage with other beginners on forums like Stack Overflow or Reddit’s r/learnprogramming.
