                 name    : "someName",
                 id      : 1241,
                 value   : 10,
             },

                 name    : "someName",
                 id      : 1242,

Use grep in jquery to select particular object

          var obj;
            obj= jQuery.grep(list, function( n, i ) {
                  return n.id==1243;
            });

       var copy= JSON.parse(JSON.stringify(obj)); // copy the object

or //var newObject = jQuery.extend(true, {}, obj);`

You can iterate over the array with a forEach, compare the Id and copy the object to a variable when matched, or, just use lodash's pluck method.

Maybe you can use clone()

Try this:

arr.push({
                 name    : "someName",
                 id      : 1241,
                 value   : 10,
             });
arr.push({
                 name    : "someName",
                 id      : 1242,
                 value   : 12,

             });
arr.push({
                name    : "someName",
                id      : 1243,
                value   : 15,
             });
var obj;
for(var i=0;i<arr.length;i++)
{
    var temp = arr[i];
    if(temp.id==1243)
    {
        obj=temp;
