one confusing thing for newbies like me:
exports.get_list = function ( cb) {
rclient.smembers("list", function(err, members) {
members.forEach(function(member){
console.log(member)
})
cb(null, 'lst')
})
}
the function(member) for 'forEach' is callback, right? then why,
cb(null,'lst') will wait until the loop is over?
