This repo is a demonstration of an edge case in how JavaScript import behaves in Node --experimental-modules versus browsers.

In a version of Node with --experimental-modules, such as 10.5.0, go to this repo and run:

node --experimental-modules index.mjs

You should see In sloppy mode printed.

Download http-server if you don’t have it already:

npm install --global http-server

Then run http-server from this repo:

http-server

You should see a message saying that the folder is now being served at an address. Go to that address in Chrome (tested in version 69).

You should see In strict mode printed.
