Using visual studio for node.js and variables in strings not printing out

I am trying to run some really basic code. I operated in Visual Studio with Ruby and I am trying to run 

function printMessage(username, badgeCount, points) {
    const message = '#{username} has #{badgeCount} total badge(s) and #{points} points in Javascript';
    console.log(message);
}
printMessage("Chalkers", 100, 2000000);

the result is:

> node test1.js
#{username} has #{badgeCount} total badge(s) and #{points} points in Javascript

I've tried replacing the #'s with $'s, and the single quotes with double quotes. If anyone could help me I'd appreciate it. I did notice if I do console.log(%s, username) it prints out Chalkers correctly, but that is not the way he is teaching it and I don't want to stray from his methods.

and for an update, I tried the code in Treehouse, and Sublime, and I am getting the same results. Is there a simple error in there somewhere I am missing?

To interpolate values into javascript template literals, you want to define you strings with backticks, and place the variables in ${}, like so:

function printMessage(username, badgeCount, points) {
  const message = `${username} has ${badgeCount} total badge(s) and ${points} points in JavaScript.`;
  console.log(message);
}

printMessage('Chalkers', 100, 2000000);

Thank you very much. It wasn't single quotes or double quotes but the hyphen key. I would have never have saw that. I need glasses very badly. Thanks again!!
