MyApp.president = Ember.Object.create fullName: (-> @get('firstName') + ' ' + @get('lastName') ).property('firstName', 'lastName')
How the hell am I suppose to read that?
Someone said that CoffeeScript is designed to be more writable than readable, and I'd tend to agree with that. But frankly, after having worked with it for the better part of a year, I prefer reading it than JS for just about everything. It's an acquired taste, but don't knock it till you try it :)
If you write beautiful javascript, you will write beautiful coffeescript and it will be 20-60% smaller. Reading less lines is less reading, this helps me.
MyApp.president = Ember.Object.create(({fullName: (function() {return this.get('firstName')+' '+this.get('lastName');}).property('firstName', 'lastName')}));
MyApp.president = Ember.Object.create fullName: (-> @get('firstName') + ' ' + @get('lastName') ).property('firstName', 'lastName')
it's not exactly a shining example of good coffeescript, but I think this is equivalent js
MyApp.president = Ember.Object.create({
fullName: function(){
return this.get('firstName') + ' ' + this.get('lastName');
}.property('firstName', 'lastName')
})
MyApp.president = Ember.Object.create
fullName: (
-> "#{@get 'firstName'} #{@get 'lastName'}"
).property('firstName', 'lastName')
Anyway, style does matter and were this line written with readability in mind you wouldn't make this mistake.
Also, I would definitely abstract over @get and property:
makeProperty = (attrs...) ->
func = () -> (@get(x) for x in attrs).join(" ")
func.property(attrs...)
MyApp.president = Ember.Object.create(
fullName: makeProperty("firstName", "lastName")
)
