methods - Accessing variables inside a Javascript promise chain -

i using chained promise in javascript (i think). there then() function in chain. want access variable inside promise, or somehow return variable via http response object.

var gettitle = function(response) {     console.log("starting gettitle. response: " + response); //this works      var horseman = new horseman();           // object headless browser      horseman         .useragent("mozilla/5.0 (windows nt 6.1; wow64; rv:44.0) gecko/20100101 firefox/44.0")         .open('http://www.google.com/ncr')         .type('input[name="q"]', 'github')         .click("button:contains('google search')")           .keyboardevent("keypress",16777221) // press enter         .waitforselector("div.g")                 .title()            // gets title of page         .then(function(t) {             console.log("title: " + t);     // works         })         .close();      console.log("title outside: " + t);     // gives 'undefined'      return t;          // returns 'undefined' } 

how can extract 't' variable? tried passing 'response' function like

.then(function(t, response) { 

but when log 'response', undefined. if pass in response object somehow, work.

if do

var test = horseman... 

test becomes promise object, doesn't contain t variable.

try returning within .finally().

    .finally(function(t){         return t;     });
