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

JavaScript and the DOM quiz: why is my answer incorrect?

The question asks: 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?

I have tried entering both of these as answers, and they are both showing incorrect:

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

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

What am i doing wrong?

Your examples use word-processor style (AKA "curly") quotes, but the quiz is expecting plain programming-style quotes.

The difference might be a bit more obvious with the syntax coloring in the code block below:

document.querySelectorAll(.student-info);  // "curly" quotes
document.querySelectorAll(".student-info");  // plain quotes

Good catch! I was doing the quiz on my iPad, and the thought of different style quotes hadn't even occurred to me. I did the quiz on my PC, with plain quotes, and it accepted the answer. Thanks!
