There is a 'script.js' file in the same folder as this file. Open it. This file is started with nodejs, so there are some differences from normal javascript, but those are minor. Complete the function that is invoked with path to a text file. This file contains numbers separated with comma. You need to return the number that occurs at highest frequency. If there is more than one - output the smaller one. There will always be at least one number and all numbers will be <= 10^9

Script output is 'undefined'
