画面晃得厉害，一会儿是天花板，一会儿是桌角。声音嘈杂，烟花声和说话声混在一起，听不清谁在说什么。屋子百来平方米，客厅里摆了三张圆桌，挤得只剩一条窄窄的过道。灯光亮得发白，照在油光的桌面上。菜已经吃得差不多，盘子叠着盘子，人挨着人坐着，有人端着酒杯站起身敬酒，有人在沙发上玩手机。热闹是真的热闹。

This fragmentation hurts portability. Code that performs well on one runtime may behave differently (or poorly) on another, even though it's using "standard" APIs. The complexity burden on runtime implementers is substantial, and the subtle behavioral differences create friction for developers trying to write cross-runtime code, particularly those maintaining frameworks that must be able to run efficiently across many runtime environments.
