数组去重
http://www.nowcoder.com/practice/0b5ae9c4a8c546f79e2547c0179bfdc2
思路：set内容唯一，将数组去重形成set对象，再对set对象结构并push到新数组中返回
Array.prototype.uniq=function(){
var arr=this
var newobj=new Set(arr)
var newarr=[]
newarr.push(...newobj)
return newarr
}
var s=[false, true, undefined, null, NaN, 0, 1, {}, {}, 'a', 'a', NaN]
var res= s.uniq()
console.log(res);
