javascript - Cannot update and use global variable in asynchronous functions -

- 

var globalvar = "";  async.series([   function(next){   db.collection.find({query}}).toarray(function(err, result) {     /*there function updates      value of globalvar "someupdatedtext"*/     console.log(globalvar); //someupdatedtext       next(err);    })   },    function(next){       console.log(globalvar); //undefined         next();   } ]);

what problem? in first function can access global variable , update value in second function globalvar returns undefined. node.js? miss?
