atomic bomb?
compose : (a -> b) -> (b -> c) -> (a -> c)
a `compose` b = \x -> b(a(x))
However, there is a whole spectrum of additionally possible functions which can be built to accept functions as arguments. Here's a couple of example: partial3 : (Integer -> Integer -> Integer) -> (Integer -> Integer)
partial3 f = f 3
map : [a] -> (a -> b) -> [b]
map [] f = []
map (x:xs) f = (f x):(map xs f)
The first one takes a function and applies an argument, 3; the next one takes a list and a function and maps the list using the provided function. The idea of functions as arguments is a very powerful one, and from my understanding one with which people sometimes struggle. All
a = b
Any
All
c = d
d = f
c = e
would be a = b
c = d
d = f
c = e
I think that it is more intuitive to segment the set as you go. console.log(process.argv.slice(2).reduce(function(a, x) {
return a + parseFloat(x)
}, 0)); T([Number, Number])(function(x) { return x; })
For this method, a function type is defined and then serves as a constructor that accepts a function as argument.
