Koa is utilizing ES6 Generators to provide an elegant way to cope with JavaScript asynchronous programming, thus you cannot see callbacks in a pureKoa application. One typical use case of ES6 Generator in Koa is middleware cascading, which allows customized middleware to execute one after another w...
Likeco,asyncawaitcan suspend a running function without blocking Node's event loop. Both libraries are built oncoroutines, but use different technologies.cousesES6 generators, which work in Node >= v0.11.2 (with the--harmonyflag), and will hopefully be supported someday by all popular JavaScri...
Geometry generators like BoxGeometry now produce a BufferGeometry. Mesh, Line and Points no longer support raycasting with Geometry. Line.computeLineDistances() no longer supports Geometry. Exporters no longer support Geometry. DecalGeometry, EdgesGeometry, WireframeGeometry, Projector, LineGeometry, Line...
So, this example shows how to write asynchronous code without callbacks using ES6 generators. ES7 takes this approach one step further by introducing the async and await keywords, and removing the need for a generator library altogether. With this capability, the previous example would look like ...
Going Async With ES6 Generators Getting Concurrent With ES6 Generators 这四篇是一个系列,把 generator 讲解得算是很透彻了。 归纳起来 generator 函数具有以下特点: 函数可暂停和继续; 可返回多个值给外部; 在继续的时候,外面也可以再传入值; 通过Generator 写的异步代码看起来就像是同步的; ...
