从提示中获取号码并循环播放

Question

I want to create a function where I get a number from a prompt and then create a loop where the number I got is the number of time the alert() executes.

I tried like this :

function game() {
    var i = prompt("Choose a number");

    for(i; i === 0; i--) {
    alert("ALERT");
    }
}

game();

But after I get the prompt(), nothing happens

Answer 1

Your for-loop condition is wrong. Should be i>0, not i===0.

Answer 2

Or...

while(i) {
    alert("ALERT");
    i--;
}

Zero evaluates as false.
