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.

  2. In Visual Studio Code, create a new JavaScript (*.js) file.
