true and false into string

Question

Hello I have class with 3 variables and one of them is boolean.

class Book {
constructor(title,autor) {
this.title = title;
this.autor = autor;
this.readed = true;
this.describeBook = function() {

console.log( "Book has title " + this.title + " ,autor is " + this.autor + " and it's been " + this.readed) ;
}
}
}
var wiedzmin = new Book('Wiedźmin', 'Andrzej Sapkowski');

wiedzmin.describeBook();

And the output I need to get is " Book has title Wiedzmin, autor is Andrzej Sapkowski and it's been readed"

But instead of "readed" I got "true" and don't have any clue how to sole this...

Any help ?

Thank you in advance

Answer 1

1. Make it a string instead of boolean. Then you can just store it as "read" or "not read," and use that value for your display easily.

2. You could run a check before the message is displayed, have it check if it's true/false, and then in a string variable have it store the correct message based upon if it was true or false.

Answer 2

That's fine. Go with the other option then.

this.readed == true ? stringVar = "read" : stringVar = "not read"

Then just use your string variable in the display method.

Answer 3

ok but my task is to create class with 3 variables and one has to be boolean so i can't change it to string

Answer 4

constructor(title,autor) {
this.title = title;
this.autor = autor;
this.readed == true ? stringVar = "read" : stringVar = "not read";
this.describeBook = function() {

console.log( "Book has title " + this.title + " ,autor is " + this.autor + " and it's been " + stringVar) ;
}
}
}
var wiedzmin = new Book('Wiedźmin', 'Andrzej Sapkowski');
