Intro to JavaScript - Functions

Question

When doing the functions practice, I put in what is in the solution; but it still comes back wrong. Any help?

function welcome(){
let name = readLine();
//rediseña la función
console.log('Welcome, user');
}

//call the function

---------------------------------------------------------------------
function welcome(){
let name = readLine();
//rediseña la función
console.log('Welcome, ${name}');
}

//call the function
welcome();

---------------------------------------------------------------------
UPDATE: Got it, I was using ' and not `

Answer 1

function welcome(){

let name = readLine();

console.log('Welcome ' + name );
}

welcome();

Answer 2

function welcome(){
let name = readLine();
//rediseña la función
console.log('Welcome,' + name);
}

//call the function
welcome();

Still said it failed. I think there might be something wrong with the lesson.
