我知道有：
Math.random()
but I could only find ways to go from 1 to 'x'
但我只能找到从 1 到 'x' 的方法

From MDN on Math.random():
// Returns a random integer between min and max
// Using Math.round() will give you a non-uniform distribution!
function getRandomInt(min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
}

I believe this would also work:
我相信这也行得通：
function randomInt(min,range) {
return Math.floor((Math.random()*(range+1))+min)
}
In your case min would be 50 and range would be 50
在您的情况下， min 为 50， range 为 50
