In this guide, I'll walk you through how to set up and effectively use GitHub Copilot for JavaScript in under 30 minutes.

Prerequisites

Before diving in, make sure you have the following:

• A GitHub account (free)
• Visual Studio Code (VS Code) installed on your machine
• GitHub Copilot subscription ($10/month or $100/year for individuals)
• Basic understanding of JavaScript syntax and concepts

4. Click on "Install."

Expected output: You should see the GitHub Copilot logo in the extensions list, indicating it's installed.

Step 2: Sign in to GitHub

1. After installation, click on the GitHub Copilot icon in the sidebar.
2. Sign in with your GitHub account when prompted.

Expected output: A confirmation message that you are connected to GitHub Copilot.

Step 3: Create a New JavaScript File

1. In VS Code, create a new file and name it app.js.
2. Start typing a function or a comment explaining what you want to achieve.

Expected output: GitHub Copilot will suggest code snippets based on your input.

Step 4: Accepting Suggestions

• Use the Tab key to accept a suggestion or the arrow keys to cycle through multiple suggestions.
• You can also type more context to refine the suggestions.

Expected output: The code snippet will populate in your file, allowing you to continue coding without interruptions.
