I think the distinction (from the OP’s perspective) is that it’s “just an app” to the end user.

When I download the Slack desktop app, I might know it’s running on electron because I’m a programmer. But I didn’t have to download and install nodejs or anything else. As far as I’m concerned it’s a completely self contained application.

The end user needn’t download and install Janet or even know that Janet exists.

That can obviously be done with any interpreted language, but Janet makes it really simple out of the box.
