    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'
