Following on from his talk on SOLID at a previous geek night, Luke Smith will be demoing "Linq for JavaScript". According to Microsoft...

LINQ is a set of extensions to the .NET Framework that encompass language-integrated query, set, and transform operations. It extends C# and Visual Basic with native language syntax for queries and provides class libraries to take advantage of these capabilities.

Luke will demo a library which takes these principles and makes them available in JavaScript. He says...

Are you familiar with Linq? Have you ever thought "hey, this is cool but I wish I could do it on the client"? Probably not. Well you can, kinda. Linq2JS is an opensource JavaScript library that brings much of the .NET Linq API to the wonderful world of JavaScript.

Still space on Tuesday for one more 5 minute talk if anyone wants to pitch in...
