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.
If you’re looking for an advanced analog instant camera, Fujifilm’s Instax Mini 99 is one to consider. At $234.95, Fujifilm’s latest instant camera is not as affordable as the Instax Mini 12 or the Mini 41, but it’s certainly a step up from the one-button point-and-click cameras given it has multiple brightness settings, focus zones, color effects, and even two shutter buttons for greater creative control. The camera even comes with a tripod socket, an aluminum extension column, and a Sports Mode designed to further reduce blur when capturing fast-moving subjects.，更多细节参见heLLoword翻译官方下载
