JavaScript CSS Selectors Quickstart The Role of Selectors in JavaScript Custom Data Attributes

Is the last code snippet comment referring to data-toggle-content?

In this part:

// assign the element with the data attribute 'data-toggle-controller' to the variable 'toggler'
var toggler = document.querySelector('[data-toggle-controller]');

// assign the element with the data attribute 'data-toggle-controller' to the variable 'toggledContent'
var toggledContent = document.querySelector('[data-toggle-content]');

Does the last comment refer to assign the element with the data attribute 'data-toggle-content' to the variable? Or I am not understanding well? Because JavaScript is selecting data-toggle-content and not data-toggle-controller.

Good eye! You might want to report this as a bug to the staff as described on the Support page.
If you're the first one to do so, you should get the "Exterminator" :beetle: badge!

Thank you Steven Parker, I'll do that.
