Return value in function from a promise block

Question

I\'m trying to write a function (using WebdriverJS lib) that iterates through a list of elements, checks the names and build an xpath locator that corresponds to that name.

Here you go, I cleaned it up a bit. This will actually return an error if one is experienced in the nested promises:

var findCreatedTask = function() {
  var Promise = require('bluebird');
  var createdTask;
  return driver.findElements(By.xpath("//div[@id='Tasks_Tab']"))
    .then(function(tasks) {
      return Promise.map(tasks, function(task){
        return driver.findElement(By.xpath("//div[@id='Tasks_Tab'][" + index + "]//div[@class='task-title']")).getText()
      }).then(function(taskTitles){
        for (let i = 0; i < taskTitles.length; i++){
          if(taskTitles[i] === 'testName'){
            createdTask = "//div[@id='Tasks_Tab'][" + i + "]";
            return createdTask;
          }
        }
      });
  });
};

You call it using

findCreatedTask.then(function(res){
   //do your thing
}).catch(function(err){
   console.error(err.stack);
});
