I have this array:

var myArray = [
                  {first_name: "Oded", last_name: "Taizi", id: 1},
                  {first_name: "Ploni", last_name: "Almoni", id: 2}
                  ];

An i want to remove the id element? I create function like this but it doesn't work correctly.

function removeKeys(array,keys){
 for(var i=0; i<array.length; i++){
    for(var key in array[i]){
        for(var j=0; j<keys.length; j++){
            if(keys[j] == key){
                array[i].splice(j, 1);
            }
        }
    }
 }
}

removeKeys(myArray ,["id"]);

The result array should look like:

[
    {first_name: "Oded", last_name: "Taizi"},
    {first_name: "Ploni", last_name: "Almoni"}
];

Use this:

myArray.forEach(function(item){ delete item.id });

Maybe with a filter on the array:

filteredArray = myArray.filter(item => return (item.id !== id));

This will return a new array without the matching element.
