You could just store your modified state to new variables though

In a live-coding session, how does the existing, running code knows that it should look at the new variables instead of the old ones?

Have a look at the video. Having immutable values doesn't mean you have immutable variables / names.

I know, the parent post was saying "you could just store your modified state to new variables", not replace what existing variables are bound to.

Or you could just make copies of state you want to keep before mutating it. Both mutable imperative code and immutable functional code can emulate each other, so which one to choose largely depends on your preferences.
