We talk functional programming in Ember, functional programming in other languages (including languages that transpile to Javascript), and functional programming in theory.
- Daniel Chappell
- 2.5 years programming exp, previous career was as a photographer
- motivation for starting programming was getting out of photography, but he soon came to love programming for itself
- functional programming
- functional style makes codebase safer and easier to change and collaborate on
- Computed Properties in Ember are pure functions
- Should separate code into functional and imperative pieces, with imperative as small as possible
- Recognized a lot of Functional philosophy in Ember
- Most Ember code can be turned into Computed Properties
- Types of Ember Code where mutation are fine: hooks and actions
- These happen based on user actions- changing the route, changing data, interacting with the screen
- Computed Properties are as trustworthy as functional properties thanks to how Ember updates them for us
- Data Flow
- Elmber <- Please create!
- Javascript is getting way better! Thanks TC39 and Babel.js!
- ES6 + Babel has made transpiling cool whereas it wasn’t before (Somewhere, Jeremy Ashkenas weeps)
- Coffeescript helped us understand Javascript
- Type systems
- Algebraic data types
- Not an expert in all of FP, but it informs how he writes code
- Javascript facilitates multi-paradigm coding
- “Patterns are language features that haven’t been implemented yet"
- Patterns are the testing ground for new ways of organizing code
- Javascript is flexible enough to emulate most other languages’ patterns
- Scheme is another example of a language that is flexible enough to emulate other languages’ patterns
- He invests in eMacs because he wants to mess around with lisp
- Q2 eBanking
- Provides high-quality banking software for small local banks that wouldn’t be able to build one themselves
- Web, Android, and iOS experiences all from the same Ember codebase
- Mission: keep small community banks/credit unions competitive with the big banks
- Jeffrey just opened a business account with a Q2-affiliated bank, and the software is great
- Ember has been great for the project- especially the commitment to semantic versioning
- They’re hiring!
- You can work with Ember all day every day
- If you’re investing your time in Ember, they want to talk to you
