Description

With NGXS v18, we have started to push towards better type safety for selectors.
The challenge is that we have users who use old mechanisms that are not type-safe and they would need guidance on converting their code to a more type-safe equivalent. Not only that, but there is an opportunity here to showcase all of the different helpers available.

We should definitely cover:

• Use a StateToken instead of the State Class to select from a state
  • and the alternative of using createSelector with some type casting to wrap an existing State Class as a type-safe selector
    createSelector([MyState], s => s as MyStateModel)
• Using createPropertySelectors to create smaller slices of your state
• Using createPickSelector to optimise a selector that has fewer dependencies
• Using createMappedSelector to combine selectors for view models, etc.
