随机抽三个人出来且不重复

<script type="text/javascript">        
        //选3个人，且不重复
        var names = ["严峫", "停停", "蒋丞", "顾飞", "江添"]
        var choice = []
        for (var i = 1; i <= 3; i++) {
            var index1 = Math.round(Math.random() * (names.length - 1 - 0 + 1) + 0)
            if (choice.every(function (item, index) {
                    return item != names[index1]
                }) == true && names[index1] != undefined) {
                choice.push(names[index1])
            } else {
                i = i - 1
            }
        }
        console.log(choice)
</script>
