javascript - socket.broadcast.to().emit() vs socket.to().emit() vs io.to().emit()

Question

What is the main difference among:

io.on('connection', socket => {

  // socket.broadcast.to(socketId).emit();
  // socket.to(socketId).emit();
  // io.to(socketId).emit();

});

All of them works as same, but what is the difference ???
