javascript modules : "export * as" in visual studio code

Question

I just joined a new project and stumbled upon the following JavaScript export syntax (global export with alias):

export * as actions from './Something.actions.js';

The syntax seems to be working, but I've never seen it before and it is marked as an error in visual studio code. Is it a valid syntax ? Can someone explain why vscode thinks this syntax is incorrect?

Answer 1

This is currently an experimental syntax (stage 1), supported via Babel but not supported natively in visual studio code at the moment.
