The following example uses JavaScript, however other languages will work similarly. GitHub Copilot provides suggestions for numerous languages and a wide variety of frameworks, but works especially well for Python, JavaScript, TypeScript, Ruby, Go, C# and C++. GitHub Copilot can also assist in query generation for databases, generating suggestions for APIs and frameworks, and can help with infrastructure as code development.

   GitHub Copilot will automatically suggest an entire function body in grayed text. The exact suggestion may vary.
