The Problem

In the initial attempt to pass the Browser variable from the function openBrowser to the monitor function, you may run into issues due to function return values and how they're structured. Here's a simplified view of your current setup:

In this example, although you're creating both a browser and page, the return statement doesn't facilitate access to these variables in the calling function. Instead, it only returns the last variable (page), causing confusion and bugs.

The Solution

To effectively pass both the browser and page variables to the monitor function, you need to structure your return statement to use an object. This allows both values to be accessible when called later in the code. Here's how you can do it:

Step 1: Modify the openBrowser Function

Instead of returning both variables separately, return them as properties of an object:

Step 2: Adjust the monitor Function

Now, in the monitor function, destructure the returned object to access both page and browser easily:

Summary of Changes

Returned an object from openBrowser containing both browser and page.

Destructured the returned object in the monitor function to grab both values without fuss.

Conclusion

Happy coding!
