Does that imply there is functionality missing from the online version of VS Code?
Mostly anything that relies on having a real system attached to it instead of the browser JS engine. Running code, or a terminal, or things that rely on the git binary. Lots of extensions are working to remove their dependencies on the local system though.
If you were to continue reading, you would be informed that many of the non-web languages don't have the same support in this version, since it can't run native language servers/any extensions that use OS-level APIs.
