Question

Describe the bug

Welcome, When I try to run this code in node.js I get an error

Code:

let OriginalTitle = Manga.prototype.title;

class Manga {

        name = getName()
        name_ar
        full_name
        chapter = getChapter();
        link = steps.trigger.event.link;
        role = "@All Series"
        title= steps.trigger.event.title;
        date = steps.trigger.event.date;constructor(){
    Compiler();
  }

It's supposed to get me out of these lines the data I exported

$.export('Manga Name',Manga.prototype.name,
    'Manga Name AR',Manga.prototype.name_ar,
    'Full name',Manga.prototype.full_name,
    'Chapter',Manga.prototype.chapter,
    'Link',Manga.prototype.link,
    'Roles',Manga.prototype.role,
    'Full Title',Manga.prototype.toString,
    'Date',Manga.prototype.date)
