On: WASM: Big deal or little deal?

I wonder if you have an object whose state has that same schema tied to a DataView offset if it'd be much different tbh.

You could create a JS object with accessor functions that stores an offset, but the object itself still takes up heap space. In Rust, it would just be a (typed) pointer to the position in the buffer and wouldn't require an allocation.

It's trivial to fix with an ECS layout, but the point is does it matter.
