javascript - Why is jshint throwing an error when i declare a class field?

Question

There is an App class in the app:

  class App {
      static cart;
      static init() {
        const shop = new Shop();
        shop.render();
        this.cart = shop.cart;
      }
    }

I'm using VSCode as IDE and jshint as a code quality tool.
Declaring of static cart; as an App class field causes the next error message in Problems panel:

(property) App.cart: any
Class properties must be methods. Expected '(' but instead saw ';'. (E054)jshint(E054)

I tried to google for this problem, but failed.
Could you tell, please, what i am doing wrong?
I'm new to JS, so maybe there is a syntax error in my code?
