JavaScript import() and export() function usage

Question

I once read about the import() and export() functions and how they relate to frames and that sort of depreciated practices. But i'm wondering if there's any practical use case for these functions on the client side.

Has anybody put import() and export() to use in an interesting way on the browser?

Is there a practical usage with say iFrames?

I was looking at the spec and the MDC docs, but there's really very little regarding these function.

Answer 1

These functions were depreciated back in Netscape 4. They actually only ever worked in Netscape 4.
