SyntaxError: Use of const in strict mode?

Question

I am trying to log in on facebook.com with selenium-webdriver.

var webdriver = require('selenium-webdriver'),

    By = require('selenium-webdriver').By,

    until = require('selenium-webdriver').until;

var driver = new webdriver.Builder()

    .forBrowser('firefox')

    .build();

driver.get('https://www.facebook.com/login');

driver.findElement(By.id('email')).sendKeys('****');

driver.findElement(By.id('pass')).sendKeys('*****');

driver.findElement(By.id('loginbutton')).click();

driver.findElement(By.linkText('Settings')).then(function(element) {

  console.log('Yes, found the element');

}, function(error) {

  console.log('The element was not found, as expected');

});

driver.quit();

 It is giving the following error:

/home/shubham/node_modules/selenium-webdriver/index.js:25

const builder = require('./builder');

^^^^^

If this is happening in nodejs, it is due to the older version of nodejs. Update node by using,

1) Clear NPM’s cache:

sudo npm cache clean -f

2) Install a little helper called ‘n’

sudo npm install -g n

3) Install latest stable NodeJS version

sudo n stable

Hope this helps!
