You can handle complex branching using standard JavaScript. Since every pipeline is just a function returning data, you can use if/else or map to return different sub-pipelines and commands from within your logic functions. Here’s an example:

const processUsersFlow = () => 
  effectPipe(
    fetchAllUsers,
    (users) => {
      const tasks = users.map(user => {
        if (user.isAdmin) return syncAdminPermissions(user); // Sub-pipeline
        if (user.isGuest) return cleanupGuestAccount(user);  // Sub-pipeline
        return notifyUser(user); // Simple Command
      });

      return Parallel(tasks); 
    }
  )();
