How to Master GitHub Copilot in 30 Minutes: Tips for Advanced Users

If you’re an advanced coder, you might find GitHub Copilot both a blessing and a curse. On one hand, it can supercharge your coding efficiency; on the other, it can lead to a dependency that stifles your problem-solving skills. In this guide, I’m going to show you how to master GitHub Copilot in just 30 minutes, focusing on practical tips that actually work, not just the shiny features you see on Twitter.

Prerequisites: What You Need Before Getting Started

Before diving into the tips, make sure you have the following:

• GitHub account: You’ll need this to access Copilot.
• Visual Studio Code: Copilot integrates seamlessly with VS Code.
• GitHub Copilot subscription: Pricing is $10/month or $100/year. There’s a free trial available, but it’s limited to 30 days.
• Basic knowledge of JavaScript, Python, or another supported language.

Step 1: Install GitHub Copilot

1. Open Visual Studio Code.
2. Go to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side.
3. Search for "GitHub Copilot" and click Install.
4. Log in with your GitHub account and authorize the extension.

Expected output: You should see Copilot suggestions as you start typing code.

Step 2: Customize Your Copilot Settings

To get the most out of Copilot, you’ll want to customize its behavior:

• Toggle Suggestions: Go to Settings > Extensions > GitHub Copilot and enable "Show Suggestions Automatically."
• Change Suggestion Display: You can choose to see inline suggestions or a separate window for easier reading.

What Could Go Wrong

If Copilot doesn’t show suggestions, make sure you’re connected to the internet and that your subscription is active. You can also check for any conflicts with other extensions.

Step 3: Use Contextual Prompts Effectively

Copilot thrives on context. Here’s how to give it the best prompts:

• Function Comments: Write a comment above your function to describe what you want it to do. For example:

  // Calculate the factorial of a number
  function factorial(n) {
  

• Code Structure: Start typing the function or logic you want; Copilot will suggest completions based on what you’ve written.

Expected Output

You should see Copilot generating code snippets based on your prompts. The more context you provide, the better the suggestions.

Step 4: Review and Edit Suggestions

Copilot is not perfect. Always review its suggestions critically:

• Check for Errors: Copilot can sometimes generate incorrect code. Always run your code and test thoroughly.
• Modify Suggestions: Don’t hesitate to tweak the code. Use Copilot as a starting point, not a final solution.

Limitations

Copilot may struggle with highly specific or complex requests. It’s not a replacement for deep knowledge of algorithms or data structures.

Step 5: Explore Advanced Features

As an advanced user, take advantage of these features:

• Multi-line Suggestions: Copilot can suggest entire functions or classes. Just start with a comment or a few lines of code, and let it complete the rest.
• Learning from Patterns: If you frequently use certain patterns, Copilot will learn and adapt its suggestions accordingly.

Our Take

We’ve found that leveraging these advanced features can significantly speed up our development process, but it's essential to be mindful of potential over-reliance.

Step 6: Combine Copilot with Other Tools

To maximize your coding efficiency, combine Copilot with other tools:
