您必须具有map和delete现有属性franchise。

var heroes = [
    {name: "Batman", franchise: "DC"},
    {name: "Ironman", franchise: "Marvel"},
    {name: "Thor", franchise: "Marvel"},
    {name: "Superman", franchise: "DC"}
];
var name = heroes.map(function(el){
  delete el.franchise;
  return el;
})
console.log(name);
