How to remove item from JS object with specific id

Question

In a given Javascript object I want to remove item with id#4. How can I do that?

var myObj =[
   {id: 1, name: "Maria"},
   {id: 2, name: "Josef"},
   {id: 3, name: "Jesus"},
   {id: 4, name: "Mohammad"}
]

something like delete myObj.id = 4??

thx in advance...

You do realize that javascript object is completely invalid ? — adeneo, Nov 08 '14 at 21:19
You (probably) mean: `[{id : 1, name : 'Maria'}]`, right? An object of objects would require each object to be mapped to a specific key, an *array* of objects would be easier. — David Thomas, Nov 08 '14 at 21:19

Thank you David Thomas - I think your link is what im looking for — RSorensen, Nov 08 '14 at 21:26
Just to clafify, you can have myObj be an object of objects, rather than an array of objects like you started, but you need to key them. — talves, Nov 08 '14 at 21:30

Let's go back to your original question of deleting an object from your object.

Let's say you created your object as:

var myObj = {};

var key = 1;
myObj[key] = {id: key, name: "Maria"};

key = 2;
myObj[key] = {id: key, name: "Josef"}

key = 3;
myObj[key] = {id: key, name: "Jesus"}

key = 4;
myObj[key] = {id: key, name: "Mohammad"}

which would look like:

var myObj ={
   1: {id: 1, name: "Maria"},
   2: {id: 2, name: "Josef"},
   3: {id: 3, name: "Jesus"},
   4: {id: 4, name: "Mohammad"}
};

Then you could delete an object from your object using it's key

key = 4;

delete myObj[key];

In this case you can key off of any value you want and not have to worry about filtering.
