Modules: do re-exports also import?

# Axel Rauschmayer (12 years ago)

My guess: if you re-export something from a module, then you still have to import it if you want to use it in that module. Is that correct?

Examples of re-exporting:

export * from "crypto";                    // re-exporting another module's exports
export { foo, bar } from "crypto";         // re-exporting specified exports from another module

That seems redundant. Maybe one could mark things that should be re-exported when importing them? On the other hand, this may be rare enough that it doesn’t warrant the extra syntax.

Correct.

Not worth it. We can consider more conveniences post-ES6 but I doubt even then this particular one would be worth it.
