JavaScript JavaScript and the DOM (Retiring) Getting a Handle on the DOM DOM Selection - More Review

What Am I Doing Wrong? All Elements in a Document using querySelectorAll.

In the final quiz of DOM Selector - More Review, I'm asked this question:

"How would you use querySelectorAll to obtain a reference to all elements in a document with the class student-info and assign it to the constant studentInfo?"

Answers I've tried (all on separate tries and all fail):

const studentInfo = document.querySelectorAll( '.student-info' );

const studentInfo = document.querySelectorAll( ".student-info" );

const studentInfo = document.querySelectorAll( .student-info );

const studentInfo = document.querySelectorAll( '.student-info' )

const studentInfo = document.querySelectorAll( ".student-info" )

const studentInfo = document.querySelectorAll( .student-info )

I'm unsure of where I'm going wrong, not getting any hints, and failing the quiz/stuck in this section if this one question is wrong. Please help!

I finally figured it out! It's been at least 30 minutes of taking that quiz over and over, but the problem was spacing.

Apparently JavaScript doesn't mind spacing but the Treehouse quiz does. The final solution was:

document.querySelectorAll(".student-info");

No spaces, anywhere. I'm updating with this comment in case anyone else is stuck here as well!

You might also wish to report this as a bug directly to the staff as described on the Support page.
