it means you use a function, which will be remove in node.js in future version,

when you won't update your node.js.

it is not important

You're most likely using

fs.writeFile('pollData.json', JSON.stringify(pollData));

inside of the pollData event. Node doesn't like it if you use writeFile without a callback anymore. All you need to do is change it to

fs.writeFile('pollData.json', JSON.stringify(pollData), function() {});
