In JavaScript, the natural primitive for "a sequence of things that arrive over time" is already in the language: the async iterable. You consume it with for await...of. You stop consuming by stopping iteration.
Quadtree-based image compression formats and level-of-detail systems all work this way. Satellite imagery, terrain rendering, and geographic information systems use quadtree decomposition to serve data at varying resolutions: zoomed out, you see large coarse blocks; zoomed in, you see fine-grained tiles. The same principle extends to three dimensions (octrees) for volume rendering and 3D spatial indexing.
