New question, so this is the array

[
    0: {
        "id" : "3"
        "name": "David",
        "age": "20"
    },
    1: {

        "name": "Micheal",
        "age": "25"
    },
    3: {
        "id" : "9"

    },
    4: {
        "id" : "12"
        "name": "Clark",

How to delete based on id when I click a button? In my app have a delete button to delete this array. I think it need to get array key in order to delete the array.

For example: I can get the id=8, but how can i get array key 2 to delete number 2 array?

If you don't understand, please welcome to comment. Thanks.

if you want to directly manipulate the contents of an array instead of returning new array, you can try this

let index = array.findIndex(obj => obj.id == objIdToDelete)
if(index != -1) { array.splice(index, 1) }

check Array.prototype.splice() to know more
