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

This release proceeds to extend the coverage of ECMAScript 5.1 

  - arguments object is added. So, it is possible to write
    functions which can take the arbitrary number of arguments
    as well as wrappers for njs built-in functions.

    function concat(sep) {
        var args = Array.prototype.slice.call(arguments, 1);
        return args.join(sep);

    > concat(' ', 'Hello', 'World', '!')
    'Hello World !'
