⭐️ static members

class A {
  static a;                 // A.a = undefined
  static b = 0;             // A.b   (static property: initialized)
  static get c() { ... }    // A.c   (static getter)
  static d() { ... }        // A.d() (static method)
}

⭐️ private static members

• accessable only within the class body.

• private members are not inherited.

class A {
  // ⭐️ "#" means "private"
  static #e;                // A.#e    (private static property: uninitialized)
  static get #f() { ... }   // A.#f    (private static getter)
  static #g() { ... }       // A.#g()  (private static method)
}
