You try writing a UI that: 1. works visually at all screen widths and resolutions 2. returned from a server with zero knowledge of said screen widths and resolutions 3. without shipping redundant assets 4. responds immediately to user input 5. but all visual updates go through this slow and crappy DOM API 6. oh, and it's all single-threaded 7. and there's no standard library for stuff like virtualized lists, modals, etc. so have fun picking your own and shipping it down 8. and your options for navigation are either losing all local state at each navigation, or writing a SPA that some neckbeards on HN hate for esoteric purity reasons
