js数组去重

为什么80%的码农都做不了架构师？>>>   

//数组去重

Array.prototype.unique = function(){
 var res = [];
 var json = {};
 for(var i = 0; i < this.length; i++){
  if(!json[this[i]]){
   res.push(this[i]);
   json[this[i]] = 1;
  }
 }
 return res;
}
var arr = [112,112,112,34,'你好',112,112,34,'你好','str','str1'];
console.log(arr.unique());
