i've been trying figure out how achieve nodejs , redis: var var1 = redisclient.get("foo"); var var2 = redisclient.get("bar"); if (var1 && var2) { do_something(); } else { do_something_else(); } i know redis calls asynchronous repeating like: var var1, var2; redisclient.get("foo", function(err, data) { var1 = data; redisclient.get("bar", function(err, data) { var2 = data; if (var1 && var2) { do_something(); } else { do_something_else(); } } }); doesn't feel right every time want access 2 variables. you can use async library control flow: async.parallel([ function(done) { redisclient.get("foo",done); }, function(done) { redisclient.get("bar",done); } ], function(err, result) { /...
