Is it a good practice intatiating or registering multiple objects at the same time

I am creating a NodeJS boilerplate, as it was a framework, and I want to "register" the routes or endpoints when the application starts. I want to have an array of route classes and then instantiate them. Similar to what NestJs does with their Controllers. Then I want to loop through the collection and create instances of each Route passed in the array. Something as the following:

class RegisterRoutes() {
  routes: [FirstRoute, SecondRoute];

  instatiateRoutes() {
    for (route in routes) {
      new route()
    }
  }
}

Is this a good practice?
