CoffeeScript and Properties
With the latest browsers, you can set properties for your objects. And as CoffeScript makes your code more beautiful, the result is quite nice.
First, create function âpropâ
prop = (who, propName, getset) ->
Object.defineProperty who, propName,
get: getset.get
set: getset.set
enumerable: true
configurable: true
Now, you can write your classes like this :
class Human
constructor:(name)->
_name = name
prop @,"Name",
get:->
console.log "get : ", _name
_name
set:(value)->
_name = value
console.log "set : ", _name
hello:->
console.log "Hi, i am # {@Name}"
And, use âsuperâ when extending classes
class SuperHeroe extends Human
constructor:(name, power)->
super name
_power = power
prop @,"Power",
get:->
_power
set:(value)->
_power = value
Use it âŠ
bob = new Human "Bob"
bob.Name = "Bobby"
bob.hello()
### Output :
set : Bobby
get : Bobby
Hi, i am Bobby
###
Personally, i find it pretty, and remember that the properties do not exist in java ;) (big troll).
Have a great weekend.
