Step-by-Step Guide to Writing Your First 10 Lines of Code

Step 1: Set Up Your Environment (15 minutes)

1. Install Visual Studio Code: Download and install it from Visual Studio Code.
2. Install GitHub Copilot: Open Visual Studio Code, go to Extensions, and search for "GitHub Copilot". Click "Install".

Step 2: Start a New Project (10 minutes)

1. Create a new folder on your computer.
2. Open Visual Studio Code and navigate to "File" > "Open Folder" to select your new folder.

Step 3: Create a New File (5 minutes)

1. In the Explorer view, create a new file named app.js (or any language file you prefer).
2. Start by typing a comment like // A simple function to add two numbers.

Step 4: Let Copilot Assist You (10 minutes)

1. After your comment, start typing function add(a, b) {.
2. You should see a suggestion from Copilot. Accept it by hitting the Tab key.
3. Continue writing the function body. For instance, you might type return a + b;.

Step 5: Test Your Code (20 minutes)

1. To test your function, add a few console log statements:

   console.log(add(2, 3)); // Expected output: 5
   console.log(add(10, 15)); // Expected output: 25
   

2. Run your code in the terminal using node app.js.

Expected Output

When you run your code, you should see:

5
25

Troubleshooting

• What could go wrong: Copilot might suggest code that doesn’t compile or runs into errors.
• Solution: If you encounter errors, double-check the syntax and logic of the suggestions. Use the documentation for the programming language you're using.

What's Next

Once you've successfully written your first lines of code, consider:

• Exploring more complex functions with Copilot.
• Diving into programming concepts like loops and conditionals.
• Building a small project to solidify your learning.

Conclusion

Using GitHub Copilot can significantly streamline your coding journey, especially as a beginner. Start by writing simple functions and gradually tackle more complex projects. Remember, Copilot is a tool to assist you, not replace your learning process.

What We Actually Use

In our experience, GitHub Copilot is great for generating boilerplate code and suggestions, but we often double-check its outputs. We also supplement our learning with resources like free coding tutorials and coding bootcamps for a more structured approach.
