var vehicle3 = {type: "Submarine", capacity: 8, storedAt: "Underwater Outpost"};

# var xs = [1,2,3]
# doubleMe(doubleMe(doubleMe(xs)))
#這樣寫法有很多缺點，太多層次要把全部層次讀完才能知道最後結果。

#在墮性語言之中
#我們要做到調用 doubleMe 時並不會立即求值，它會說“嗯嗯，待會兒再做！”
#在真正執行時只會是一個平面，像 xs *2 *2 *2;

(a, b, c) --> a * b * c
#代替了
(a) -> (b) -> (c) -> a * b * c

#舉例
#var times = function(x) {
#  return function(y) {
#    return x*y;
#  }
#}
#console.log(time(2)(3)) // 6  

times = (x, y) --> x * y
times 2, 3       #=> 6 (参数足够时是一个普通的函数,返回计算后的结果)
double = times 2 #参数不够时,会返回一个部分应用函数.相当于JavaScript中的double = times.bind(null,2)
double 5         #=> 10 (相当于times(2)(5))
