Chalkers won't be printed after node app.js

In this video I used a workspace with the following code:

function printMessage(userName, badgeCount, points) {
    let message = '${userName} has ${badgeCount} total badge(s) and ${points} points in Javascript.';
    console.log(message);
}

printMessage('chalkers', 100, 2000000);

After adding the code and saving app.js I went to the console (in the workspace) and executed app.js but got

${userName} has ${badgeCount} total badge(s) and ${points} points in Javascript.

This is not a plausible respone, why did I get it?

When you use template interpolation, your template string must be enclosed in accents ("back-ticks") instead of apostrophes ("single quotes") or double quotes. Otherwise the placeholders are treated as just part of the string.

    let message = `${userName} has ${badgeCount} total badge(s) and ${points} points in Javascript.`;

Oh, I confused the backticks with tildes, so I thought I should use "forwardTicks" (single quotes). Thank you Steven.
