Yes you right. But what are you think about react reducer switch like this? :

const someReducer(state, {type, payload}) {
  switch (type) {
    case SET_SOME: return {...state, some: payload}
    case WORK_WITH_OTHER: return {...state, other: payload, some: false}
    // ... and so on
    default: return state;
  }
}

Looks like a regular reducer to me... how is this related to what we were talking?

reducer is looks same as ternary with two function, just case use one condition with many pure function.

Again, this is because you care about the result of the function. My take is: use statements for side effects and expressions for pure functions.
