How can I log or dump data when working with JavaScript using AngularJS, Karma, and Jasmine?

Usually, when I want to record data in JavaScript, I opt for logging it to the console with 

console.log("What I had for dinner yesterday");

However, while exploring a Karma/Jasmine unit testing video tutorial for AngularJS hosted by Vojta Jína, I came across a different logging method - using window.dump.

I'm curious to know what advantages this type of logging offers compared to just using console.log. I found information about dump function on window in this MDN article, but it seems like the logs appear directly in my terminal window where my tests run. Additionally, there is some guidance on how to dump in the AngularJS documentation, but I'm not sure if it's the same technique demonstrated by Vojta Jina.

If anyone can shed light on the logging method used by Vojta and provide further resources or insights into proper logging practices in JavaScript, I would greatly appreciate it.

It seems like utilizing window.dump with redirection - you can check out more information on this here

The browser.dom.window.dump.file preference redirects the output of window.dump() calls to a specified file address when browser.dom.window.dump.enabled is true. Any changes made require an application restart.

Therefore, it appears that you have the ability to bind the dump function to any desired output stream.

You may also refer to this link for further details.

In order to view console outputs on Windows, a console needs to be present. If not already available, closing and reopening the application with the command line parameter -console should create one. On other operating systems, launching the application from a terminal is sufficient.

To redirect console output to a file, run firefox without the -console option and use the syntax to redirect stderr and stdout to a file as follows:

firefox > console.txt 2>&1

If you wish to display console messages in the same console used for launching the application, consider using the Gecko Console Redirector
