我有一个带有 name 的对象数组和 age属性(property):

[
  { name: "Matthew", age: 23 },
  { name: "James", age: 20 }, 
  { name: "Daniel", age: 25 },
  { name: "Joshua", age: 22 }
]

我要删除 age来自所有对象的属性并在控制台中打印

[
  { name: "Matthew" },
  { name: "James" }, 
  { name: "Daniel" },
  { name: "Joshua" }
]

遍历您的数组并使用 delete关键词。

let array = [
  { name: "Matthew", age: 23 },
  { name: "James", age: 20 }, 
  { name: "Daniel", age: 25 },
  { name: "Joshua", age: 22 }
]
array.forEach(function(v){ delete v.age });
console.log(array);
