如何在javscript中删除数组中的数组

Question

let array = [
    {id: "455", some: [{id: "21"}]},
    {id: "12", some: [{id: "21"}]},
    {id: "12", some: [{id: "21"}]}
];

array.slice("some");

在这里，我试图删除数组中的一个数组，但是它不起作用。

在这里，我只想从所有对象中删除some数组。

Answer 1

您可以使用rest语法和一些Object Destructuring：

let result = array.map(({ some, ...rest}) => rest);

演示：

let array = [
   {id: "455", some: [{id: "21"}]},
   {id: "12", some: [{id: "21"}]},
   {id: "12", some: [{id: "21"}]}
];
      
let result = array.map(({ some, ...rest}) => rest);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }

Answer 2

一行：

let array = [{id:"455",some:[{id:"21",},],},{id:"12",some:[{id:"21",},],},{id:"12",some:[{id:"21",},],}];


array.forEach(it => delete it.some);

console.log(array);

Answer 3

您可以使用map和destructuring仅取出所需的属性和值。

let array = [{id:"455",some:[{id:"21",},],},{id:"12",some:[{id:"21",},],},{id:"12",some:[{id:"21",},],}];
      
let result = array.map(({id}) => ({id}));

console.log(result);
