Without the break statement, this loop would run forever. The break condition checks if count exceeds 3. $ node main.js 0 1 2 3 Break in nested loopsWhen used in nested loops, break only exits the innermost loop. main.js for (let i = 0; i < 3; i++) { for (let j = 0; j...
In this example, the break statement terminates the infinite loop when the user input num is 0. If it isn't 0, the loop keeps taking input and printing it to the screen. Working of JavaScript break Statement The image below shows the working of the break statement in for and while loop...
正常情况下break只会退出最近的一个循环,以上例子会返回96。但标记loop标记了最外层的for循环,所以break后便退出了整个循环。 一个循环内也可以有多个标记。 // 示例 let count = 0; loop1: for (let i = 0; i < 10; ++i) { loop2: for (let j = 0; j < 10; ++j) { for (let k = 0;...

In a non-trivial loop body, it is easy to overlook a break or a continue. A break in a loop has a dramatically different meaning than a break in a switch-statement (and you can have switch-statement in a loop and a loop in a switch-case). 在不规整的循环体中,很容易忽略掉break和...
