How do I remove an object from an array with JavaScript

Question

I have a JavaScript object that looks like this:

id="1";
name = "serdar";

I also have an Array that contains several of the above things. 

How do I delete an item from an array like this:

obj[1].remove();

Answer 1

Splice is effective:

var arr = [{id:1,name:'serdar'}];
arr.splice(0,1);
// []

Arrays should not be deleted using the delete operator. 

delete does not remove an entry from an Array; instead, it replaces it with undefined.

var arr = [0,1,2];
delete arr[1];
// [0, undefined, 2]

But perhaps you'd like something like this?

var removeByAttr = function(arr, attr, value){
    var i = arr.length;
    while(i--){
       if( arr[i] 
           && arr[i].hasOwnProperty(attr) 
           && (arguments.length > 2 && arr[i][attr] === value ) ){ 

           arr.splice(i,1);

       }
    }
    return arr;
}
