How to declare local function inside ES6 class?

Question

I have a function that can be used only inside a class and don\'t want it to be accessible outside the class.

class Auth {
  /*@ngInject*/
  constructor($htt         


        

Answer 1

You could use a Symbol:

const localFunc = Symbol();
class Auth {
  /*@ngInject*/
  constructor($http, $cookies, $q, User) {
    this.$http = $http;
    this.$cookies = $cookies;
    this.$q = $q;
    this.User = User;

    this[localFunc] = function() {
      // I am private
    };
  }
}
