Java的while循环中的continue语句导致无限循环 [英] Javascript continue statement in while loop causes an infinite loop

问题描述

我正在尝试使用continue语句创建while循环.但是，这似乎导致了无限循环，我不知道为什么.

I'm trying to create a while loop with a continue statement. However it seems to be causing an infinite loop and I can't figure out why.

下面的代码对我来说似乎应该以var tasksToDo从3开始，然后递减到0并跳过数字2.

The code below to me seems like it should start with the var tasksToDo at 3 then decrement down to 0 skipping number 2 on the way.

var tasksToDo = 3
while (tasksToDo > 0) {
    if (tasksToDo == 2) {
        continue;
    }
    console.log('there are ' + tasksToDo + ' tasks');
    tasksToDo--;
}

推荐答案

conitnue，将返回while循环.并且taskToDo的递减永远不会超过2.

conitnue, will go back to the while loop. and tasksToDo will never get decremented further than 2.

var tasksToDo = 3
while (tasksToDo > 0) {
if (tasksToDo == 2) {
 tasksToDo--;             // Should be here too.
 continue;
}

console.log('there are ' + tasksToDo + ' tasks');
tasksToDo--;
}
