I don't think this part of JavaScript will ever change. Node does not
modify the JavaScript language it uses.
Lua does this though if you want to try luvit.io (node ported to lua). It
has syntax sugar to make defining and calling context-first methods easier.
-- This is lua code, not JS
local Point = {}
-- constructor
function newPoint(x, y)
local obj =setmetatable({}, Point)
-- This is really obj.initialize(obj, x, y)
obj:initialize(x, y)
end
-- This is really Point.initialize = function (self, x, y) ...
function Point:initialize(x, y)
self.x = x
self.y = y
end
I think a more relevant question for the node list would be preference in
using "this" and shared function prototypes vs storing state in closures.
I find both patterns very useful in node code and I often mix them.
