such as clicking a button. in javascript, when an event occurs, the app fires the event, which is kind of a signal that an event has occurred. the app then automatically responds to the user in the form of output, thanks to event handlers in javascript. an event handler is essentially ...

(1)V8引擎解析JavaScript脚本。 (2)解析后的代码,调用Node API。 (3)libuv库负责Node API的执行。它将不同的任务分配给不同的线程,形成一个Event Loop(事件循环),以异步的方式将任务的执行结果返回给V8引擎。 (4)V8引擎再将结果返回给用户。 除了setTimeout和setInterval这两个方法,Node.js还提供了另外两个...
单线程意味着,javascript代码在执行的任何时候,都只有一个主线程来处理所有的任务。 而非阻塞则是当代码需要进行一项异步任务(无法立刻返回结果,需要花一定时间才能返回的任务,如I/O事件)的时候,主线程会挂起(pending)这个任务,然后在异步任务返回结果的时候再根据一定规则去执行相应的回调。
