|

| 10 | EFFECT:
|
| 11 | modulePostLoadAction is run every time the module is loaded.

|
| 13 | Initially, moduleState is {}.
|
| 14 |
|
| 15 | moduleState is the same object every load:
|
| 16 | modulePostLoadAction can modify moduleState and it will persist through every reload.
|
| 17 |
|
| 18 | modulePostLoadAction is responsible for any and all
|
| 19 | update actions required due to the module load.
|

|
| 21 | NOTE:
|
| 22 | If _module is not hot, modulePostLoadAction will be invoked once with an empty {}.
