Class attribute / instance attribute

Language Help JavaScript
1

Hello,

While I am working on this project:
(https://www.codecademy.com/journeys/front-end-engineer/paths/fecj-22-front-end-development/tracks/fecj-22-javascript-syntax-part-iii/modules/wdcp-22-find-your-hat-10850a06-4cc1-43f0-95d4-6d824fd91120/projects/find-your-hat),
I wanted t make a distinction between class attributes and instance attributes, like in Python, for example:

Python:

class Field:
   hat = '^'
   hole = 'O'
   fieldCharacter = '░'
   pathCharacter = '*'

   def __init__(self):
      self.field = []
      self.boundarieX = 0
      self.boundarieY = 0
      self.positionX = 0
      self.positionY = 0

So, in JS I did:

class Field {
   hat = '^';
   hole = 'O';
   fieldCharacter = '░';
   pathCharacter = '*';

   constructor() {
      this.field = [];
      this.boundarieX = 0;
      this.boundarieY = 0;
      this.positionX = 0;
      this.positionY = 0;
   }
}

But, if I try to access to attributes who are not declared in the constructor, I can.
Is there a way in JS to “isolate” attributes only for the class?

Maybe you can use static fields.
if you had something like

class Field {
   static hat = '^';

then you’d be able to access that static variable by using Field.hat

here’s some references for JavaScript that may help:
MDN reference - static
MDN reference - Public class fields

It will make the job. I knew about the static methods but not about the static attributes, thank you for your help.
