• increment/decrement statement:迭代语句,它定义循环变量的更新; • code to be executed:要执行的代码块,不断重复执行的部分。 例如,我们想要将特定集合中的所有数字相加,可以使用for循环来完成这项任务: 1.计算一个数组中所有数字的总和: AI检测代码解析 var array = [1,2,3,4,5]; var sum = 0;f...
以下是一个示例代码,演示了如何使用For Loop迭代多个输入,并限制迭代的数量为3: 代码语言:txt 复制 var inputs = [1, 2, 3, 4, 5]; // 多个输入的数组 var limit = 3; // 迭代数量限制 for (var i = 0; i < inputs.length; i++) { if (i >= limit) { break; // 达到限制,终止循环 ...
setTimeout() }, 3000) } myLoop(); // start the loop 您还可以通过使用自调用函数来整理它,将迭代次数作为参数传递:(function myLoop(i) { setTimeout(function() { console.log('hello'); // your code here if (--i) myLoop(i); // decrement i and call myLoop again if i > 0 }, ...
// Step 2. Create the FOR loop /* The starting point of the loop will be (str.length - 1) which corresponds to the last character of the string, "o" As long as i is greater than or equals 0, the loop will go on We decrement i after each iteration */ for (var i = str.len...

4. For For loop is used to iterate a set of statements based on a condition. for(Initialization; Condition; Increment/decrement){ //code } 5. While While is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known...
For example, if you want to increment a number by 1, you can write either of the following commands:Copy number = number + 1; number++; Similar to operator “++”, which increments a number by 1, you can use operator “--" which decrements a number for 1. So, again, both of ...
As a comparison to the originals, here are the operations being performed per iteration for these loops: One comparison (i == true) in the control condition One decrement operation (i--) One array lookup (items[i]) One function call (process(items[i])) The new loop code has two fewer...
