ES6/Arrow函数版本基于Francis的代码（即顶级答案）：

const randomIntFromInterval = (min, max) => Math.floor(Math.random() * (max - min + 1) + min);

范围[a，b]内的加密强随机整数（假设：a<b）

let rand=（a，b）=>a+（b-a+1）*crypto.getRandomValues（新Uint32Array（1））[0]/2**32|0console.log（兰特（1,6））；

我写了一个更灵活的函数，它可以给你随机数，而不仅仅是整数。

function rand(min,max,interval)
{
    if (typeof(interval)==='undefined') interval = 1;
    var r = Math.floor(Math.random()*(max-min+interval)/interval);
    return r*interval+min;
}

var a = rand(0,10); //can be 0, 1, 2 (...) 9, 10
var b = rand(4,6,0.1); //can be 4.0, 4.1, 4.2 (...) 5.9, 6.0

返回1到10之间的随机数：

Math.floor((Math.random() * 10) + 1);

结果可能是：3.

或使用lodash/descore：

_.随机（最小值，最大值）

如果您想覆盖负数和正数，并确保其安全，请使用以下方法：

JS解决方案：

function generateRangom(low, up) {
  const u = Math.max(low, up);
  const l = Math.min(low, up);
  const diff = u - l;
  const r = Math.floor(Math.random() * (diff + 1)); //'+1' because Math.random() returns 0..0.99, it does not include 'diff' value, so we do +1, so 'diff + 1' won't be included, but just 'diff' value will be.
  
  return l + r; //add the random number that was selected within distance between low and up to the lower limit.  
}

Java解决方案：

public static int generateRandom(int low, int up) {
        int l = Math.min(low, up);
        int u = Math.max(low, up);
        int diff = u - l;

        int r = (int) Math.floor(Math.random() * (diff + 1)); // '+1' because Math.random() returns 0..0.99, it does not include 'diff' value, so we do +1, so 'diff + 1' won't be included, but just 'diff' value will be.
  
        return l + r;//add the random number that was selected within distance between low and up to the lower limit.      
}
