根据键而不是值从数组中删除对象？

Question

I have an array of the object where I want to remove an object based on key? I tried with filter, omit in lodash but nothing worked. the description can be in any position

Input

input = [{product: "abc", value: "123"},{name: "def", value: "234"},{description: ["abd123"]}]

Expected Output

output = [{product: "abc", value: "123"},{name: "def", value: "234"}]

const result = input.filter(el => el.key !== description)

Answer 1

You'd declare array this way:

const input = [{product: "abc", value: "123"},{name: "def", value:"234"},{description: ["abd123"]}];

and delete your object using some function as

let output = input.filter(object => !object.hasOwnProperty("description"));

so that

output = [{product: "abc", value: "123"},{name: "def", value:"234"}];

 const input = [{product: "abc", value: "123"},{name: "def", value:"234"},{description: ["abd123"]}]; let output = input.filter(object => !object.hasOwnProperty("description")); output = [{product: "abc", value: "123"},{name: "def", value:"234"}]; console.log(output);

Answer 2

if you would like to remove any object has key use hasOwnProperty to check

let input = [{product: "abc", value: "123"},{name: "def", value: "234",description:0},{description: ["abd123"]}]


let output = input.filter(el=> !el.hasOwnProperty('description'))

Answer 3

你可以这样做：

input.filter(el=> !el.description)
