The Writer is not a concrete class. Any object that implements write(), end(), and abort() can be a writer making it easy to adapt existing APIs or create specialized implementations without subclassing. There's no complex UnderlyingSink protocol with start(), write(), close(), and abort() callbacks that must coordinate through a controller whose lifecycle and state are independent of the WritableStream it is bound to.
The design of Web streams predates async iteration in JavaScript. The for await...of syntax didn't land until ES2018, two years after the Streams Standard was initially finalized. This timing meant the API couldn't initially leverage what would eventually become the idiomatic way to consume asynchronous sequences in JavaScript. Instead, the spec introduced its own reader/writer acquisition model — and that decision rippled through every aspect of the API.。业内人士推荐搜狗输入法2026作为进阶阅读
