ProtocolJS is an informal fork of Gozala's protocol module with some variation in implementation to
$ npm install protocoljs
A protocol is a set of function interfaces.
var protocol = ;var Enumerable =;
Protocols enable polymorphism in a flexible way where the interface definition is decoupled from the implementations for any number of types.
;Enumerable; // => 1Enumerable; // => [2, 3]Enumerable; // => [1, 2, 3, 1, 2, 3]
You can tie any number of types to a protocol.
;Enumerable; 'a'Enumerable; 'bc'Enumerable; 'abcabc'
You can also tie any number of protocols to a type.
var RightEnumerable =;;RightEnumerable; // => 'c'RightEnumerable; // => 'ab'
Finally, you can re-open protocols and extend their interfaces.
;;;Enumerable; 1 2Enumerable; 'ab'
