The While Loop Thewhileloop loops through a block of code as long as a specified condition is true. Syntax while(condition) { // code block to be executed } Example In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less th...
loop 关键字告诉 Rust 一遍又一遍地执行一段代码直到你明确要求停止。Rust 提供了一种从代码中跳出循环的方法。loop 循环,相当于一个 while true,需要程序自己 break: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 fnmain(){letmut counter=0;letresult=loop{counter+=1;ifcounter==10{breakcounter*2;}...

JavaScript中的循环是一种重复执行特定任务的语句。它主要用于操作数组和类似数组的对象,比如字典、集合等。JavaScript提供了三种不同的循环控制语句:for循环、while 循环 以及 do-while 循环. For循环(for loop):for循环是最常用的循环控制语句,它可以在特定的范围内重复执行一定的代码。for语句的结构如下: ...
In JavaScript do while loop executes a statement block once and then repeats the execution until a specified condition evaluates to false.Syntaxdo { statement block } while (condition); In while loop, the given condition is tested at the beginning, i.e. before executing any of the statements...
函数首先检查条件函数的返回值,如果为真,则执行执行函数,并在延迟时间后再次调用delayedWhileLoop函数。这样就实现了延迟执行While循环的效果。 需要注意的是,使用延迟执行While循环时,需要确保条件函数在每次调用时都能返回正确的结果,以避免无限循环。此外,延迟时间应根据具体情况进行调整,以平衡执行速度和系统资源的使用...

JavaScript While 循环JS For JS Break 只要指定条件为 true,循环就可以一直执行代码。while 循环 While 循环会在指定条件为真时循环执行代码块。 语法 while (条件) { 需要执行的代码 } 实例 本例中的循环将继续运行,只要变量 i 小于 5: while (i<5) { x=x + "The number is " + i + ""; i++...
