javascript死循环while #JavaScript中的死循环:深入理解`while`循环在编程中,循环是一个非常常见的操作。它使得我们能够重复执行代码块,直到满足某个条件为止。不过,如果不小心,我们可能会陷入一个死循环(Infinite Loop),这会导致程序不响应甚至崩溃。今天,我们将集中讨论在JavaScript中如何使用`while`循环,并了解死循环...
var i = 1; // set your counter to 1 function myLoop() { // create a loop function setTimeout(function() { // call a 3s setTimeout when the loop is called console.log('hello'); // your code here i++; // increment the counter if (i < 10) { // if the counter < 10, ...
action, delay); }, delay); } } var i = 0; delayedWhileLoop( function() { return i < 10; }, function() { console.log(i); i++; }, 1000 );
打开atomic-sleep模块的源码,在index.js文件中,我们看到其主要逻辑是依赖了Atomics.wait方法,该方法会监听一个Int32Array对象的给定下标下的值,若值未发生改变,则一直等待(阻塞event loop),直到发生超时(由ms参数决定定): constnil=newInt32Array(newSharedArrayBuffer(4))functionsleep(ms){// 参数校验相关代码略...

这种行为适用于大多数循环(比如while和for-of循环)… 但是它不能处理需要回调的循环,如forEach、map、filter和reduce。在接下来的几节中,我们将研究await如何影响forEach、map和filter。 在forEach 循环中使用 await 首先,使用forEach对数组进行遍历。 const forEach = _ => { ...

The code I have written involves looping through an array and removing a random item during each iteration until the loop length becomes 0. While I am unsure of the best method to accomplish this in Angular1.x or plain JavaScript, I would like to add a delay or sleep in each iteration....
The sleep function is for demonstration purposes to simulate slow execution of the long-running function and wouldn't be present in production code. When a component calls stopFn, the longRunningFn is signalled to abort via the while loop conditional check on AbortSignal.aborted....
JavaScript是没有sleep方法的,正因为它是单线程执行的,sleep方法是没有意义的。如果非要sleep,我们只能实现一个没有意义的伪sleep: 1 2 3 4 5 6 7 8 functionsleep(time) { varstart =newDate().getTime(); while(true) { if(newDate().getTime() - start > time) { ...
