  You can use runtimes that Lambda provides for JavaScript (Node.js), TypeScript, Python, Java, 
  
  Python, Go, C#, and PowerShell, or you can build your own custom runtime environment inside of a 
  container. 
  
  If you package your code as a .zip ﬁle archive, you must conﬁgure your function to use a runtime 
  
  that matches your programming language. For a container image, you include the runtime when 
  
  you build the image.
