That browser world would of been glorious without HTML5. Where Javascript wasn't in the browser and Tcl was (it was a contender); we would be working with plugin based browsers rather than built-in to the hood. That in turn would enable you to process incoming documents based in XSLT however you desired.
It would of been glorious having any programming language usable within the browser. Craft your own features rather than what's given to you now. It's only now that we're gaining the ability to use other languages via WASM.
Tcl was a contender to Javascript in the browser but Javascript won because it didn't require a plugin. And as Tcl never became the browser's default scripting environment juxtaposition Flash eventually lost because the browser platform evolved to make its proprietary plug-in unnecessary
