Wii U: Open Web Developer Console for Debugging

[VGMoose]

On the Wii U, if you open the browser and go to the Settings, there's an option to "Enable Developer Tools". This starts an http server which you can visit from a computer on the same network, and view web inspector information about pages being rendered by the Wii U browser.

Example output from Google Chrome on PC after visiting the IP that the Wii U gives you in its browser settings:

Here we can debug and see the full error that the Wii U webkit instance hit when trying to render the page. In this case, it does not support the let keyword, which was introduced in ES6 in around 2015. Previously this part of the page was broken, but with this information, this bug is able to be addressed.

It's a pretty cool feature tucked away in settings, and would love to have something similar for the Switch browser.
