These things are actually pretty related: JS isn't particularly slow as a language; it only gets slow on the web because every time JS code touches the DOM/CSS a part of layout and style needs to be recomputed.
Theoretically they'd complement each other, but in practice I imagine UIs for super-resource-constrained set-top boxes are already written in pretty efficient JavaScript.
