Cant import non-workspace projects and cant use javascript in the editor

How do I turn a project I already have into a workspace for the editor?
Also how do I use javascript instead of typescript in the editor?

Hi @Mahmlo

Unfortunately there is no way to transform an existing project to an editor project as all code is highly linked to the architecture of editor projects.
Also only TS is supported using the Editor to attach scripts
