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.

What’s the trade off? Communication happens over processes that trade strings. This introduces overhead and means there is no clear contract on what sorts of error cases can arise. Concretely, evaluation goes from O(10ms) to O(100ms). This is still interactive but worth calling out.
