The primary signal is desiredSize on the controller. It can be positive (wants data), zero (at capacity), negative (over capacity), or null (closed). Producers are supposed to check this value and stop enqueueing when it's not positive. But there's nothing enforcing this: controller.enqueue() always succeeds, even when desiredSize is deeply negative.

“本来应该从从容容、游刃有余！现在是匆匆忙忙、连滚带爬！”这本来是台湾地区一位民意代表王世坚批评台北市市政管理混乱说的话，但是由于他讲话的语气相当有节奏感，富有张力，后来还被博主改编成了歌曲《没出息》，于是迅速火爆全网。不过最近，国务院台办发言人表示，这个人一边靠着“没出息”的改编热度，在网络上蹭眼球，一边又大放厥词刷存在，这种自相矛盾的作秀，真是没出息。
If such a thing existed, languages could generate these artifacts and browsers could run them, without any JavaScript involved. This format would be easier for languages to support and could potentially exist in standard upstream compilers, runtimes, toolchains, and popular packages without the need for third-party distributions. In effect, we could go from a world where every language re-implements the web platform integration using JavaScript, to sharing a common one that is built directly into the browser.
