Tips for adding a new variable and its value to an existing object at the end

            [{ date="4/7/2012",  username="dealcloud",  user_id=304378189, location="New York"},
             { date="4/7/2012",  username="rizwanharun",  user_id=18932327, location="Los Angeles"},
            { date="4/7/2012",  username="aimtoendhunger",  user_id=122384145, location="Chicago"},
            { date="4/7/2012",  username="Sindy882",  user_id=705160297, location="Miami"}}]

Is there a way to add a new object with variables and values at the end of each existing object? For example, I would like to include 'location' along with date, username, and user_id in each object.

Thanks in advance for the assistance!

Answer №1

Be advised: Your json syntax needs adjusting.

Try implementing the following:

var jsonData = [{ "date":"4/7/2012",  "username":"dealcloud",  "user_id":304378189},
             { "date":"4/7/2012",  "username":"rizwanharun",  "user_id":18932327
            },{ "date":"4/7/2012",  "username":"aimtoendhunger",  "user_id":
            122384145},{ "date":"4/7/2012",  "username":"Sindy882",  "user_id":
            705160297}}];
for(var j = 0; j < jsonData.length;j++) {
    jsonData[j].location = "New location";
}

Answer №2

It's important to keep in mind that objects do not follow a specific order.

let array = [{}, {}, {}];

for (index in array) {
  array[index]['another_key'] = 'another value';
}
