TransformStream creates a readable/writable pair with processing logic in between. The transform() function executes on write, not on read. Processing of the transform happens eagerly as data arrives, regardless of whether any consumer is ready. This causes unnecessary work when consumers are slow, and the backpressure signaling between the two sides has gaps that can cause unbounded buffering under load. The expectation in the spec is that the producer of the data being transformed is paying attention to the writer.ready signal on the writable side of the transform but quite often producers just simply ignore it.
《呼兰河传》中关于祖父的后花园有一段描写：“后花园”的花开了，就像花睡醒了似的。鸟飞了，就像鸟上天了似的。虫子叫了，就像虫子在说话似的。一切都活了。都有无限的本领，要做什么，就做什么。要怎么样，就怎么样。都是自由的。
