我的代码没有加载（卡在do / while循环？）

Question

I've been trying to make "a program" that basically keeps "throwing dice" (randomize the value) until you get snake eyes, and when you do it's supposed to show how many times the dice were thrown. However, it doesn't load. What did I do wrong?

var countRolls = 0;
do {
var die1 = (Math.random() * 6) + 1; 
var die2 = (Math.random() * 6) + 1;
++countRolls;
} while (die1 != 1 || die2 != 1);
console.log(countRolls);

I've tried opening it in Chrome/Firefox and it'll just load forever, and I won't be able to open the console. Tried it in JSFiddle, and it became unresponsive.

Answer 1

因为Math.random()返回一个double ，所以die1和die2的概率几乎为0％都为1

Answer 2

Your loop will never end because you add one to the random function and the stop condition is just testing for not 1 but this will not happen.

Add console.log(die1,die2); to your do {}
