Please elaborate, I don't get what you are suggesting.

JavaScript was hacked together in short time for the browser. You can't get any less server-side than that?

Might be a reference to Netscape Enterprise Server[1], which had server-side JS in 1995?

I did server-side programming in JavaScript in the late 90s. In retrospect it was a bad idea, but people were doing it. Note: this shouldn't be confused with the more recent node.js version of server-side JS.

Livewire, it was called, back when you bought your browser in a box at Best Buy.
