Nice example. I used to use 'K in keyof state as k extends string? 'get${k}':never' the intersection with string approach is much clearer..

Damn good stuff! Do you know how to create mapped types that contain only a single key from an object?

Another awesome TS content. Do you use TS since it came out?

This works at type level, but runtime example is not provided, how can we use this 'personStore' const value?
This code fails to work on runtime as is. Because there was no real runtime value provided to personStore.
Could you please be kind, and share example with working runtime value assigned to personStore?
