JavaScript有一个基于事件循环的并发模型,事件循环负责执行代码,收集和处理事件以及执行队列中的子任务。 并发模型与事件循环(Concurrency model and Event loop) 包含对 栈堆 队列的理解 运行时(runtime)概念 可视化描述 Frame 帧;Stack 栈;Heap 堆;Queue 队列 栈 函数调用形成了一个由若干帧组成的栈,比如: functi...
Concurrency model and Event Loop 翻譯不完整。請協助翻譯此英文文件。 JavaScript 的並發模型是基於 event loop,其在運作上跟 C 或是 Java 有很大的不同。 執行環境概念(Runtime concepts) 下面的內容解釋了一個理論模型,現代 JavaScript 引擎著重實作及優化了描述過後的語意。

The JavaScript Execution Model The first chapter of this book explored the state of JavaScript concurrency. Generally speaking, dealing with concurrency in JavaScript applications is anything but a trivial matter. There's a lot to think about when writing concurrent JavaScript code, and the kind of...
Node.JS (JavaScript) Personally I find Vert.x to be quite interesting (especially for a Java / JVM dinosaur like me). Actors vs. Channels Actors and channels are two similar examples of assembly line (or reactive / event driven) models. In the actor model each worker is called an act...
这个算法事实上假设了load/store具有硬件原子性,然而现代的硬件中,因为relaxed memory consistency model的存在,这个算法已经不适用。 Memory Consistency 内存一致性模型描述多核同时读写同一块内存时的行为。理想情况下,读操作将会读到最后一次对该内存进行写的值。
