 These flags will be given to the Elm program, allowing you to do some setup work in JS first.

If you want to reinitialize your Elm component, you can add a different `key` to the old and new components so the old one is destroyed and replaced by the new one.

 In the `setupPorts` function, we first subscribe to the `numActiveTodos` port. Whenever the number of active todos changes, we will run that function and log the number on the console. After that, we send two values through the `todos` port. This will add both of these into the model *and* trigger the `numActiveTodos` callback twice.
 
-**Note:** Once the `ports` function has been used to initialize the component, it will never be used again. Providing a new function does nothing. If you want to change your ports, you should save the `ports` object into your `state` so you can mess with it later.

+Once the properties are initialized, they will never be used again. Changing `flags` or `ports` will do nothing. So here are two tricks that may help you out:

+  - If you want to reinitialize your Elm component, add a different `key` to the old and new components. This way old one is destroyed and replaced by the new one.
