  3. 3. JavaScriptNo longer ‘hide-this-div-then-animate-that’De-facto language of the webHard challenges for large scale appsJS as a runtime environment?
  4. 4. CoffeeScript - The AwesomeCompiles to JavaScriptYou can still use any of the JS librariesEncourages good JS patternsMakes JS code shorter and more readableCompilation and debugging can be a pain
  5. 5. CoffeeScript - The Awesomehttp://coffeescript.orghttp://js2coffee.orgShould You Learn CoffeeScript?What are the pros and cons of CoffeeScript?Dropbox dives into CoffeeScriptWhy I prefer JavaScript over CS?The Little Book On CoffeeScriptLess Typing Bad Readability
  6. 6. The FrameworksBackbone.js Angular.jsKnockout.js Spine.jsEmber.js MeteorRich JavaScript Applications – the Seven Frameworks
  7. 7. Backbone.jsProvides REST-persistable modelsWith strong client side routing solutionDoes nothing towards automated UI syncModel, Collection, View, Router
  8. 8. Knockout.jsFocuses on automated UI bindingsDeveloper writes the modelsNo routing (eg. Crossroads.js, Sammy.js)Observables, ObservableArrays
  9. 9. Meteor & Ember.jsMeteor Crazy amazing framework from the future Bridges the server side runtime with client sideEmber.js Biggest framework with the most functionality Ember makes all the common solutions
  10. 10. CSS can be FUNLESS, SASS Meta languages interpreted to CSS Variables, Mixins, Nested rules, Functions & Operations An Introduction To LESS, And Comparison To SassTwitter Bootstrap Toolkit for kickstarting CSS for websites and web apps

  13. 13. QA != FarmvilleManual testingAutomated UI testingUI Unit TestingJS Runtime Error Tracking http://errorception.com
  14. 14. Automated UI TestingIf a bug pops up, add as a step to a scenarioRun them daily on every browsersRun the related scenarios before check inCucumber framework integrated to CI http://cukes.info
  15. 15. JavaScript Unit TestingJasmine BDD framework Testing the Models and Lists Integrated to CISinon.js library Stubs, spys, faking, mocking, etc
  16. 16. Cool StuffHTML5Event driven programmingMeasure all the things!D3.js
  17. 17. HTML5Actually there are useful and working APIs! Drag And Drop API: even IE supports it File API: For file management. IE? Nope History API: History manipulation. IE? Nope Local Storage API: IE8+http://www.html5rocks.com http://diveintohtml5.info
  18. 18. Event Driven JavaScriptKill the callbacks nested callbacks nestedcallbacks. Time to write maintainable code.http://twitter.github.com/flight/Amazon: Async JavaScript
  19. 19. Measure All The ThingsMeasure users, trends and performance Google Analytics New Relic KISSmetrics Errorception Optimizely, Chartbeat, etc...
  20. 20. D3.js - The Chart ToolManipulating documents based on data https://github.com/mbostock/d3/wiki/GalleryTons of charting libraries based on D3 NVD3.js - Reusable charts for d3.js
