{ Code: Impossible }

I've finally pushed one of my side-projects, the JavaScript Object Query library to 1.0! I'm pretty psyched since I've been meaning to do this ever since I blogged about it back in February. You can download the 1.0 release here (minified) and here (normal). What is Jsoq?
Jsoq is a port of Linq to Objects to JavaScript. Under the covers jSoq is a bunch of wrapper code for dealing with arrays in JavaScript. Features for v1.0

• Doesn't mess with "$" variables so it works with jQuery, Mootools, etc.
• using select() you can have Jsoq return only certain members from each object in it's query set
• use built-in filter methods first(), last(), skip(), take() or roll your own using where()
• ability to add functionality to your returned object via the extendEach() method
• you can use $q as a shortcut for the jsoq.From() method
• inner and left joins are now supported with the leftJoin() and innerJoin() methods

A very basic code example
Below is what I would call the common jsoq use case. The code below will find the first item that has a value property with a length greater than 3, and return an object containing its id property.

var somearray = [
    { value: "one", id: 1 }, 
    { value: "two", id: 2 }, 
    { value: "three", id: 3 }, 
    { value: "four", id: 4 }
];

var result = $q(somearray)
                    .where(function(item) {
                        return item.value.length > 3;
                    })
                    .first()
                    .select("id");

alert(result.id); // alerts "3"

For a full list of features and more code examples check out the documentation on the official Jsoq wiki, it's a bit sparse right now but I'll be adding more content in the near future.
