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 = _________
Why it's impossible to see a correct answer when I don't know it?

document.querySelector() and document.querySelectorAll() uses type and/or css selectors to select elements on a webpage. So the answer for this question would be:
const studentInfo = document.querySelectorAll(".student-info");

PHP Development Techdegree Graduate 48,635 PointsDo you know how to use querySelector() to select a class? It's the same thing, except it's querySelectorAll() instead of just querySelector();

2,381 PointsHi Joseph, thank you for your answer. Yes I'm trying to "use querySelectorAll()" in this way:
const studentInfo = document.querySelectorAll();
but I'm not sure what I should to put in the parenthesis. What is the solution?
Thanks

9,260 PointsI had the same answer except I didn't have the dot before student-info. Why is it .student-info and not just student-info?

document.querySelector()anddocument.querySelectorAll()uses CSS selectors to select DOM elements. The.in CSS is the class selector. SO in this example ofconst studentInfo = document.querySelectorAll(".student-info");you're selecting all DOM elements with the class.student-info. Hope that explanation helps.
