js weight to an array of objects containing

For complex array contains objects, create a new array using a simple indexOf new array to determine whether it contains an array element is not applicable, reduce the need to use this method:

var array = [
{"sort":"1","name":"老王"},
{"sort":"2","name":"老李"},
{"sort":"3","name":"老张"},
{"sort":"4","name":"老岳"},
{"sort":"5","name":"老刘"},
{"sort":"1","name":"老王"},
];

unique(array);
//利用reduce方法遍历数组,The first parameter is a function reduce traverse to be executed, the second parameter is the initial value of the item 
to true'':? obj [next.sort] =
      obj [Next. the Sort](item, Next) {function= ary.reduce (
      ARR{};obj =varUNIQUE (ARR) {
      function && item.push(next); 
         return item;
      },[]); 
      return arr;
}
