A somewhat successful attempt at implementing point-free notation in Javascript using proxies. It works perfectly for regular functions, but somehow fails for higher order ones.
Example usage:
let p = pfree (global) (x => x)
// You can define things in point-free notation inside this with block
with (p) {
add = x => y => x + y
succ = add (1)
five = succ . add (2) . succ (1)
}
console.log(five) // 5Does not work properly for higher order functions (this might change one day):
// Church encoding
with (p) {
flip = f => x => y => f (y) (x)
Const = a => b => a
dot = f => a => b => f(a(b))
ap = f => g => x => f (x) (g (x))
zero = flip (Const)
succ = ap (dot)
// The number n is represented by running a function n times over some input
num = n => n (x => x + 1) (0)
console.log ( num ( succ ( succ ( succ (zero) )))) // 3
console.log ( num . succ . succ . succ (zero) ) // [Function]
}Use this in production code. Even if I eventually fix higher order functions, it is abuse of the Javascript language and against all conventions- your co-workers will hate you.
