🧑‍💻 GitHub Copilot – Your In-Editor Coding Assistant

🧠 Best For:

• Live coding assistance in VS Code, JetBrains, Neovim, etc.

• Speeding up day-to-day coding workflows

• Learning new programming languages or unfamiliar frameworks

• Writing and fixing test cases, boilerplate, or documentation

• Pair programming with AI that understands your context

⚙️ Why It’s Powerful:

GitHub Copilot is built using OpenAI’s Codex, fine-tuned on billions of lines of public code.

The magic is that it:

• Predicts and completes code in real-time as you type

• Understands your project context (especially with Copilot X or Enterprise)

• Explains tricky code and suggests improvements

It’s like having a junior dev buddy who reads your mind and finishes your functions.
