Auto-completion of code

I think it would be better to implement auto-completion/suggestion, which is available in most IDEs. The students can know the correct variable/method to type if implemented.

I am willing to help implement that but I don't know how. It would be great if someone would work on this and guide me along the way.

Thanks

The issue names no files, tests, or entry points. Start by locating the live editor's code-editing and suggestion integration, then define the supported completion behavior and how it will be verified before implementation.
