What is GitHub Copilot

GitHub Copilot is an AI tool that uses machine learning models to suggest entire lines of code or complete functions based on comments and code you've already written. It is trained on a large portion of public code from GitHub and other sources, giving it an impressive understanding of common coding patterns.

It integrates directly with Visual Studio Code, JetBrains IDEs, and other major development environments, providing suggestions in real time.

Key Features

Real-Time Code Suggestions

Copilot provides inline code suggestions as you type. It can predict the next line, complete entire functions, and even generate boilerplate code.

Multi-Language Support

It supports dozens of programming languages, including Python, JavaScript, TypeScript, Go, C++, Ruby, and more.

Comment-Based Coding

Write a comment describing what you want the code to do, and Copilot will attempt to write the code for you.

IDE Integration

Copilot works inside popular code editors like Visual Studio Code, Neovim, JetBrains, and GitHub Codespaces.

Learning and Adapting

Over time, Copilot adapts to your coding style and preferences, improving the accuracy and usefulness of its suggestions.
