Interacting with JavaScript, DOM and Web APIs?

Are there any plans to support interaction with JavaScript, DOM and Web APIs with ThinScript? I'd be really interested in seeing the performance benefit that low-level WebAssembly can bring when creating large web apps. I'd also be interested in exposing API end-points for other JavaScript libraries to consume/interact with the compiled application.

I haven't got a huge experience in this field and I'm not even sure it might all be possible/feasible, but I thought it might be a good discussion point.
