所以setTimeout(function, delayTime) 中的延迟参数并不代表函数执行后的精确时间延迟。...事件循环所以,事件循环其实就是js代码借助与浏览器API向消息队列中丢入一些回调函数,等待执行栈放空自己的时候,把消息队列中的回调函数压入到执行栈中执行的这么一个机制。...紧接着runWhileLoopForNSeconds(3);被压入了执...
You can build recurrence rules to specify when a job should recur. For instance, consider this rule, which executes the function every hour at 42 minutes after the hour: varschedule=require('node-schedule');varrule=newschedule.RecurrenceRule();rule.minute=42;varj=schedule.scheduleJob(rule,funct...

From the Run widget list on the toolbar, select the newly created Attach to Node.js/Chrome configuration and click next to it. The debugger stops at the breakpoints that you put in your code in IntelliJ IDEA. Now, every time you make any changes to the code and save them Ctrl0S, nod...
