# JavaScript Code

> Execute arbitrary Javascript code

The JavaScript Code node is able to execute arbitrary, pure javascript code and provide its results to the next nodes.
Currently this node does not accept any library imports and/or calls.

## Input

It's important to say that you can also interpolate data from previous nodes in the JavaScript Code node by using the following notation:

```javascript theme={null}
$nodes['Node Name'].property
```

```javascript icon="square-js" lines Example theme={null}
// If you have a Message Received trigger node called 'Message Received',
// you can do:

if ($nodes['Message Received'].contact.firstName === 'Cogfy') {
  return 'That is me!'
} else {
  return 'That is not me'
}
```

## Output Schema

The output schema defines the properties that will be available to the next nodes.

<ResponseField name="result" type="any">
  The `result` field will be whatever type you put in your `return` statement.

  In the example above, the `result` is of type `string`.
</ResponseField>
