Check Key words in a text entry with JavaScript

Hello Guys! I,m Guio!

I was trying to make a texty entry quiz and my goal was to check if the answer is corret by checking if they used some key words.

I found this guy on youtube (https://youtu.be/R4SLR6UB-44) that used JavaScript to do that in three diferent ways, I was abble to make only the firt one work, can someone help please?

this is my code fore de second method:

var answer  =  getVar("TextEntry2");
var words  =  ["cat",  "dog"];
var containsWords  =  words.every(word => new RegExp('\\b${word}\\b', 'i').test(answer));
setVar("key_words1", containsWords);

    Copy and paste the code below exactly as it is:

    var answer = getVar("TextEntry2");
var words = ["cat", "dog"];
var containsWords = words.every(word => new RegExp(`\\b${word}\\b`,'i').test(answer));
setVar("key_words1",containsWords);

    Issue: ${word} doesn’t interpolate inside quotes, so the regex looks for the literal text ${word} instead of the actual word.
    Fix: Use backticks (template literals) so word is injected correctly.
