How to pass a slice?

[dakom]

Looking at the nalgebra docs it seems that it can extract a slice (or pointer) from its matrices

What would be the (or one) correct way to pass these slices to JS?

Thanks!

Currently the best way to do so is to invoke an imported function inline rather than returning it directly to JS. #918 was an attempt to implement this and otherwise I think this is covered by #811 so we can convert it to a JsValue and return it, so I'm gonna close in favor of #811!
