Sentiment analysis with IBM Watson

I am trying to build a sentiment analysis bot with IBM Watson for slack. https://api.slack.com/tutorials/watson-sentiment#setting_up_your_request_url

I got stuck quite early, as when running the node script of index.js, I keep getting this error:

SyntaxError: Unexpected token 'const'

I checked my code with the example github, and it doesn't look like I have any typos, here is the .js file:

const express = require('express');
const bodyParser = require('body-parser');
const app = express();
...

const server = app.listen(5000, () => {  
  console.log('Express server listening on port %d in %s mode', server.address().port, app.settings.env);});

app.post('/event', (req, res) => {
  if (req.body.type === 'url_verification') {
    res.send(req.body.challenge);
  }});

In order to connect and verify with Slack API this had to be added:

app.use(bodyParser.json());

the "..." on the 4th line is not supposed to be in your actual code. It's just a shorthand for you to delete, meaning that other libraries or variable definitions could appear there.

Just remove the "..."
