  INSTALLING NODE Use NodeVersionManger you can thank me later
 https://github.com/creationix/nvm curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.25.4/install.sh | bash 
 nvm install iojs
 nvm install 0.10
 nvm use 0.10

  NODE PACKAGE MANGER NPMinstalled with Node.js
 https://www.npmjs.com/
 Manage your package dependencies & a little bit more

• 11.
  NODE PACKAGE MANGER package.json 
 npminstall 
 will install everything in the package.json file. npm install <package_name> 

• 12.
  GULP & GRUNT BUILDTOOLS Thecool kids use gulp, it is newer and shiny.
 Gulp streams file generation instead of writing temp copies.
 Gulp is much faster, Grunt has more plugins http://gruntjs.com/http://gulpjs.com/
• 13.
  JASMINE & MOCHA TESTFRAMEWORKS Holy war like JUnit andTestNG Jasmine is older, more documentation and has mocking and assertions built in
 Mocha is newer and lets you choose what mocking and assertions libraries you want http://jasmine.github.io/ http://mochajs.org/

  SO MANY CHOICESFOR SELENIUM & JAVASCRIPT
• 15.
  WEBDRIVER.JS https://code.google.com/p/selenium/wiki/WebDriverJs Official Selenium ProjectJavascript bindings
 Most downloaded selenium package
 Difficult to find online community support
 Project Lead - Jason Leyba - California - Google 
 Late to the party - don’t get confused with Webdriver.JS that is now Webdriver.io
• 16.
  WEBDRIVER.IO http://webdriver.io/
 Has the coolestlogo!
 Started before Selenium Project javascript bindings and was called webdrver.js 
 Awesome documentation!
 Nice framework
 Project Lead - Christian Bromann - Berlin - Sauce Labs 

• 17.
  WD.JS http://admc.io/wd/ 
 Framework Appiumproject uses for testing Appium
 Project Lead - Adam Christian - California - Sauce Labs
 A little obscure, mostly developed specifically for Adam’s and few others needs.
• 18.
  NIGHTWATCH.JS http://nightwatchjs.org/
 The simplest toget up and running
 Includes test runner, test framework and assertion framework
 Good Documentation and Community
 Test framework limited functionality compared to Mocha & Jasmine Project Lead - Andrei Rusu - Norway - Confirmit 

• 19.
  PROTRACTOR.JS https://angular.github.io/protractor/#/ 
 Wrapper aroundwebdriver.js
 Best community!
 Project Lead - Julie Ralph - Washington - Google
 Mainly created for AngularJS apps and has ability to know AngularJS app state
 Can be used with non-angular sites, simple config change
 Best built in parallel running ability

  ASYNCHRONOUS If you arenot use to programming asynchronously that can be a challenge to get use to
• 21.
  ASYNCHRONOUS the answer
• 22.
  THE CALLBACK
• 23.
  CALLBACK HELL async1(function(input, result1){ async2(function(result2) { async3(function(result3) { async4(function(result4) { async5(function(output) { // do something with output }); }); }); }); })
• 24.
  THE PROMISE A promiseis an object that represents a value, or the eventual computation of a value
 Promises save you from callback hell
 Promises make it easier to read code
 Promises come with ES6
 You can also use libraries like Q https://github.com/kriskowal/q with older versions of node.js
