Question: Here is my JS object:

```
  var request = {
    "name": "Name",
    "id": 3,
    "rules":[
      {
        "name": "Rule name",
        "tags": [
          {
            "tagId": 1,
            "variables":[
              {
                "variable": "var1",
                "matchType": "Regex"
              }
            ],
            "condition": false,
          }
        ],
        "ruleSetId": 3,
      }
    ]
  }

```

How can I add a new property `"value": "some value"` to the `variables` objects? For example, after I add this property, the object should look like this:

```
  var request = {
    "name": "Name",
    "id": 3,
    "rules":[
      {
        "name": "Rule name",
        "tags": [
          {
            "tagId": 1,
            "variables":[
              {
                "variable": "var1",
                "matchType": "Regex",
                "value": "some value"   <----------
              }
            ],
            "condition": false,
          }
        ],
        "ruleSetId": 3,
      }
    ]
  }

```

I tried the following but it adds me an additional object that only contains `{"value": "some value"}` :

```
  request.rules[0].tags[0].variables.push({
    "value": "some value"
  });

```

Answer: 
```
request.rules[0].tags[0].variables[0].value = "some value";

```

Or if you want to append this new property in all variables:

```
var target = 'value';

for (var i = 0; i < request.rules[0].tags[0].variables.length; i++) { 
  if (request.rules[0].tags[0].variables[i][target]) { 
    break;
  }
}

request.rules[0].tags[0].variables[i][target] = "some value";

```
You're almost there.

```
request.rules[0].tags[1].variables['value'] = 'some value';

```
