1. 无限循环(Infinite Loop) 无限循环是指程序中的一个循环结构没有明确的退出条件,导致它会一直运行下去,除非被外部因素(如用户中断、系统错误等)强制停止。 基础概念 循环结构:JavaScript 中常用的循环结构有for、while和do...while。 退出条件:正常情况下,循环应该有一个或多个条件来判断何时停止执行。
let count = 0; while (true) { console.log("This is an infinite loop, count:", count++); if (count === 10) break; // 假设我们只想循环10次 } 2. 表示无限大 虽然JavaScript没有专门的“无限大”值,但可以使用Infinity来表示。 应用场景:数学计算中需要表示一个比任何有限数都大的值时。
