Answer 1

You have defined function outside the class. That should be inside the class.

class Add {
constructor(...words) {
this.words = words;
}

print(){
var str = this.words.join("quot;);
var b = "quot;+str+"quot;;
console.log(b);//
}
}

I don't know what my error

Answer 3

in addition to declaring the print function as standalone one instead of class (prototype) attached, it lacks closing curly bracket ^^

if you want to declare the function outside of class body, you must use the underlying prototype of constructor (public) function:

class Add {
/* ... */
}
Add.prototype.print = function () {
/* ... */
};
