njs-0.2.6

[Dmitry Volyntsev]

Hello,

I'm glad to announce a new release of NGINX JavaScript module (njs).

This release proceeds to extend the coverage of ECMAScript 5.1 
specification.

  - Added initial support for extending the existing prototypes. So,
  generic functions can be added to extend functionality of built-in
  types.

   : > String.prototype.myUpper = function() {return this.toUpperCase()}
   :   [Function]
   : > 'abc'.myUpper()
   :   'ABC'
