# goBack(\[options])

Returns the main resource response for the navigation, or `null` if the navigation is impossible (e.g., when already at the beginning of the session history).

Navigates back in the browser’s session history. This method is safer than using `page.evaluate(() => window.history.back())` which can cause race conditions.

|-------------------|--------|---------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| options           | object | `null`  |                                                                                                                                                                                            |
| options.timeout   | number | `30000` | Maximum operation time in milliseconds. Pass `0` to disable the timeout. The default value can be changed via the methods listed below. Setting the value to `0` will disable the timeout. |
| options.waitUntil | string | `load`  | When to consider operation to have succeeded. See [Events](#events) for more details.                                                                                                      |

### Methods to Change Default Values

You can change the default value using one of the following methods:

- [browserContext.setDefaultNavigationTimeout(timeout)](/docs/k6/next/javascript-api/k6-browser/browsercontext/setdefaultnavigationtimeout/)
- [browserContext.setDefaultTimeout(timeout)](/docs/k6/next/javascript-api/k6-browser/browsercontext/setdefaulttimeout/)
- [page.setDefaultNavigationTimeout(timeout)](/docs/k6/next/javascript-api/k6-browser/page/setdefaultnavigationtimeout/)
- [page.setDefaultTimeout(timeout)](/docs/k6/next/javascript-api/k6-browser/page/setdefaulttimeout/) |

### Events

> Caution
> 
> Avoid using `networkidle` for testing. This event might never fire on websites with high network activity. Instead, use web assertions to assess when the page is ready

You can set the event to one of the following:

- `'domcontentloaded'` : The `DOMContentLoaded` event fires.
- `'load'` : The `load` event fires.
- `'networkidle'` : There are no network connections for at least 500 ms.
