How to remove JSON object based on id from array type script [duplicate]

Question

I have an cart array into which I am pushing the elements like:

 cart = [];
 this.cart.push(item);

I also want to delete the element from this cart[] array based on id, the objects structure looks like:

[
    {
        id:1,
        imageUrl: "http://lorempixel.com/100/100/people?1",
        author: "Windward",
        handle: "@windwardstudios",
        body: "Looking for a better company reporting or docgen app?",
        totalLikes: 0,
        iLike: false
    },
    {
        id:2,
        imageUrl: "http://lorempixel.com/100/100/people?1",
        author: "Windward",
        handle: "@windwardstudios",
        body: "Looking for a better company reporting or docgen app?",
        totalLikes: 0,
        iLike: false
    }
]

I'm doing the pop operation to remove the object that is added to array, but unfortunately this is removing the last inserted item. Which I don't want.

this.cart.pop();

How can I do this in typescript?

There is no JSON in this question. JSON is a set of rules to format a string so it can be parsed as an object. The objects themselves are just objects. — Cerbrus

var jsonString = '{ "foo": "bar" }' <-- that is JSON. var obj = { foo: "bar" } <-- that's an object. What you have there isn't JSON. — Cerbrus

Sorry for that..but i am using var data = JSON.parse(JSON.stringify(item)); to convert it into JSON — Rohitesh

You can use Array filter

    var idToDelete = 1;
    this.car = this.cart.filter(item=>item.id !=idToDelete );
