It is also necessary to emphasize that many optimizations are only possible in parts of the spec that are unobservable to user code. The alternative, like Bun "Direct Streams", is to intentionally diverge from the spec-defined observable behaviors. This means optimizations often feel "incomplete". They work in some scenarios but not in others, in some runtimes but not others, etc. Every such case adds to the overall unsustainable complexity of the Web streams approach which is why most runtime implementers rarely put significant effort into further improvements to their streams implementations once the conformance tests are passing.

而当伊朗防空系统被瘫痪和廓清后，F-35I便降低隐形要求，外部挂载弹药，和F-15、F-16等战机执行类似的精确打击任务。唯一不同的是，拥有先进传感器的F-35I还兼顾情报收集（例如拍摄目标区域的照片和规划攻击路线等），在预警机、电子战飞机和空中加油机保障下对伊朗实施不间断的“穿透式打击”。，详情可参考爱思助手下载最新版本
