Cannot get the app.js to work

I am building the console application in the node.js course to print out the users--name, badge count and points. I have just started and cannot get the console to print out the parameters when I am calling the function. It will print the message just as is in the console.

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

printMessage("chalkers", 100, 6905);

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

printMessage("chalkers", 100, 6905);

is there is any error in console.

I found this very frustrating and while the answer is here its not very clear so I thought I spell it out for people like me who were confused by what a back tick was. A back tick is a ( ` ) not a ( ' ). The key you're looking for is found above the tab key on an English (windows/3rd party keyboard) I can't confirm if this is true for Mac users or other European countries. However after a little deep dive I did some places saying that it is alt + 9 on a European keyboard can someone confirm?

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

printMessage("chalkers", 100, 6905);

Thanks @David Smith. It would have been helpful for that to be specified in the video.

For anyone wondering where to find this on a British or US-English keyboard, refer to this thread.

yes, I should have thought of that :) Thank you Ashish, it worked.

Also, I realized that I was using normal quote marks and not backticks. I added the backticks and it worked.

This is what happened to me. Thank you. I put the backticks in there and it worked.

Nope, it prints out the message as is. ${username} has ${badgeCount} total badges and ${points} points in JavaScript.

I am calling the function with the specified parameters but the message is not getting updated. :(

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

printMessage("chalkers", 100, 6905);

May be template literal is not compatible with your browser so I will suggest you to try old concatenation part.

The tips above worked for me when I added the backticks at the front and end of the message variable. Thanks for the assist!

So why are we using back ticks and brackets, I feel like that came from no where? Did I miss something

Hey Mike, these are template literals in the teachers notes they have linked to a video about template literals it is new in ES6. They are much easier because they eliminate the need for concatenation in most places.
