9. “[…] The reason I built Handlebars in the first place wasn't an attempt to create a "logicless" template engine. I build Handlebars so that I could start from zero and build up syntactic structures that would support data binding from the get-go.” Yehuda Katz
10. • Handlebars • HTMLBars • Glimmer

24. Functional Relationship
25. A functional relationship is a relationship in which the value of one variable varies with changes in the values of a second variable.
26. A relationship is considered functional when there is respect, accountability and resilience. A functional relationship offers an emotionally safe environment for the people involved and respects privacy of space.
27. Functional Paradigms
28. "If someone says to you that JavaScript is a functional language, slap him in the face.” Garrett Smith
29. • data driven architecture • immutable data • pure functions/components • @@iterator / transducers • type systems
30. Immutable.js bower install immutable
31. // app/helpers/get-in.js import Ember from 'ember'; const { makeBoundHelper } = Ember.HTMLBars; export default makeBoundHelper(function([scope, path]) { return scope.getIn(path.split('.')); });
32. <ul> {{#each tickets as |ticket index|}} <li> {{input type="checkbox" checked=(get-in ticket 'isSelected') change=(action select index)}} <div> {{get-in ticket 'origin.name'}} -> {{get-in ticket 'destination.name'}} </div> <div> Departure: {{moment (get-in ticket 'departure')}} </div> <div> Arrival: {{moment (get-in ticket 'arrival')}} </div> </li> {{/each}} </ul>
33. Components
34. Helpers
35. Actions
36. @@iterator
37. transducers bower install transducers-js
38. Transducers are composable algorithmic transformations. They are independent from the context of their input and output sources and specify only the essence of the transformation in terms of an individual element.
39. Flow npm install babel-plugin-typecheck
