JavaScript是一种以事件驱动(Event-driven)的开发语言。事件驱动是程式设计的主要流程,是由图形化使用者操作界面(UI)的交互事件为主要核心,藉由事件的触发动作(鼠标点击、键盘输入等等)或是感应器的信息,以此启动程式。 维基百科对它的解释是: 事件驱动程序设计(英语:Event-driven programming)是一种电
要理解event loop首先需要了解的就是event driven programming(事件驱动的编程)。这个在1960年代就已经被人们所熟知。如今,event-driven proggramming被广泛的应用在UI处理中。javascript主要用在处理DOM中。 定义非常简单:event-driven programming就是程序的控制流程是由事件或者状态的改变决定的。主要的实现机制就是用一...

虽然JS运行在浏览器中是单线程的,但是浏览器是事件驱动的(Event driven),浏览器中很多行为是异步(Asynchronized)的,会创建事件并放入执行队列中。浏览器中很多异步行为都是由浏览器新开一个线程去完成,一个浏览器至少实现三个常驻线程: JS引擎线程 GUI渲染线程 ...
