手写获取随机数函数

[Hongbusi]

function getRandom (min, max) {
  return Math.floor(Math.random() * Math.abs(max - min + 1) + min)
}

[Rainer-Yu]

function getRandom() {
    const ran = parseInt(10*Math.random())
    const ran2 = parseInt(10*Math.random())+1
    const temp = crypto.getRandomValues(new Uint32Array(ran))[ran-1]
    return parseInt((temp+'').substring(0,ran2))
}
