node> Thank you, Brain, for building us redis-node-client

redis.get("greeting", function(err, reply) { sys.puts(typeof(reply)); })

node> object // oops, it's an object instead of string

redis.get("greeting", function(err, reply) { sys.puts(sys.inspect(reply)); })

// What's this? a buffer representation?
node> { '0': 84, '1': 104, '2': 97, '3': 110 ... , length: 51 }

I see, thanks for confirming!

node.js api has documented buffer.toString(), my ignorance:
