# Output to the browser console

You can use `console.log()` or `print()` in the Code node to help when writing and debugging your code.

For help opening your browser console, refer to [this guide by Balsamiq](https://balsamiq.com/support/faqs/browserconsole/).

## console.log (JavaScript) <a href="#consolelog-javascript" id="consolelog-javascript"></a>

For technical information on `console.log()`, refer to the [MDN developer docs](https://developer.mozilla.org/en-US/docs/Web/API/Console/log).

For example, copy the following code into a Code node, then open your console and run the node:

```js
let a = "apple";
console.log(a);
```

## print (Python) <a href="#print-python" id="print-python"></a>

For technical information on `print()`, refer to the [Real Python's guide](https://realpython.com/python-print/).

For example, set your Code node **Language** to **Python**, copy the following code into the node, then open your console and run the node:

```python
a = "apple"
print(a)
```

### Handling an output of `[object Object]` <a href="#handling-an-output-of-object-object" id="handling-an-output-of-object-object"></a>

If the console displays `[object Object]` when you print, check the data type, then convert it as needed.

To check the data type:

```python
print(type(myData))
```

#### JsProxy <a href="#jsproxy" id="jsproxy"></a>

If `type()` outputs `<class 'pyodide.ffi.JsProxy'>`, you need to convert the JsProxy to a native Python object using `to_py()`. This occurs when working with data in the n8n node data structure, such as node inputs and outputs. For example, if you want to print the data from a previous node in the workflow:

```python
previousNodeData = _("<node-name>").all();
for item in previousNodeData:
	# item is of type <class 'pyodide.ffi.JsProxy'>
	# You need to convert it to a Dict
	itemDict = item.json.to_py()
	print(itemDict)
```

Refer to the Pyodide documentation on [JsProxy](https://pyodide.org/en/stable/usage/api/python-api/ffi.html#pyodide.ffi.JsProxy) for more information on this class.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/build/code-in-n8n/cookbook/code-node/output-to-the-browser-console.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
