underscore

[dvv]

Mind to publish it also in form of underscore.js plugin?
TIA,

Not sure how you wanted it done, but due to the async'ness, you won't be able to mix and match zo and underscore functions like this:

_([1, 2, 3]).
    zoMap(function (item, mapTo) {
        setTimeout(function () {
            mapTo(item + 1);
        }, 500);
    }).each (function (item) {
        console.log(item);
    });

There's no guarantee that the mapTo will be executed before the each. Once in async-world, always in async world. So, the best I can do is something like this:

var _ = require('underscore'),
    zo = require('zo').zo;

_.mixin({
    zo: function (items) {
        return zo(items);
    }
});

_([1, 2, 3])
    .zo()
    .map(function (item, mapTo) {
        setTimeout(function () {
            mapTo(item + 1);
        }, 500);
    })
    .results(function (items) {
        console.log(items);
    });

Where the call to .zo() starts the zo namespace and it's all zo methods from there on.
