示例1: function

return {
past: newPast,
present: previous,
future: [ present, ...future ]

case 'REDO':
const next = future[0];
const newFuture = future.slice(1);
return {
past: [ ...past, present ],
present: next,
future: newFuture

default:
// Delegate handling the action to the passed reducer

if (present === newPresent) {
return state
}
