javascript - node.js - making result available globally (Request module) -


i'm trying process returned json result request need expand scope outside request call. declared data variable empty string , assign result data doesn't print result.

how can accomplish this?

module.exports = function(callback) {      var request = require("request")     var url = "http://sheetsu.com/apis/94dc0db4"     var data = "";      request({         url: url,         json: true     }, function (error, response, body) {          if (!error && response.statuscode === 200) {             callback(body)              data = body;          }     })      console.log(data);   }

your script executed in order:

  1. request() executed
  2. console.log(data)
  3. request() callback function, asign data value

if want print data, must inside request callback function. async module, useful when performing async tasks, specially if need perform tasks in specific order , use data requests.

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
