How do I solve this problem?

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?

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

Hi Angelica,

your code is nearly correct...

When you use querySelector or querySelectorAll you have to select the element the same way you select in css. Which means if you select an id you write document.querySelector("#id-name"), if you select a class you write document.querySelectorAll(".class-name") etc.

Notice the dot "." in front of the class name (just as when you select a class in css) - that's all you are missing.

Blessings from Berlin and happy java-scripting, Nils
