Match Single Characters Not Specified. What is different from other JS environments?

So far this has been a great section. However when I use the exact code in freeCodeCamp elsewhere I get a null result. What am I doing incorrect???


let quoteSample = "3 blind mice.";
let myRegex = /change/; // Change this line
let result = myRegex; // Change this line

You have not changed any of the original challenge seed code. What have you tried that is not working?
