数组key值下面value值一样的去重

var arr2 = [

  { name: "name1", num: "1" },

  { name: "name2", num: "11" },

  { name: "name3", num: "12" },

  { name: "name4", num: "13" },

  { name: "name2", num: "1" },

  { name: "name6", num: "12" }

]

function arrayUnique2(arr, name) {

  var hash = {};

  return arr.reduce(function (item, next) {

    hash[next[name]] ? '' : hash[next[name]] = true && item.push(next);

    return item;

  }, []);

}

console.log(arrayUnique2(arr2, "name"));

console.log(arrayUnique2(arr2, "num"));


 

 var obj = {C旅游_I景点: 1, C旅游_I毕业旅行: 0.55, C旅游_I旅游攻略: 0.26};
        var arry=[]
        for (const key in obj) {
            var new_arry = {tag:'',score:0};
            new_arry.tag = key;
            new_arry.score = obj[key];
            arry.push(new_arry);
        }
        console.log(arry);
