What is the leading LINQ for JavaScript library?
I'm looking for a JavaScript library that will allow me to query complex JSON objects using a LINQ-like syntax. A quick search found a couple of promising options that look they might offer what I need:
- Does any one have any experience using them?
- What are some pros and cons?
- Is the performance comparable?
- Does the function-passing syntax of LINQ to JavaScript offer any hidden benefits (I personally find the syntax of jLinq more appealing on first glance)?
- What have you found lacking in either project?
- Did you ever try contacting the authors? How responsive were they?
- What project is more widely used?
I think it will be the first one to get a thorough try-out.
Answer
You might want to check out linq.js. It follows the .NET lambda syntax and looks to be well integrated in a Microsoft environment.
LINQ for JavaScript - http://linqjs.codeplex.com/
Pros
- Implements all .NET 4.0 methods
- Complete lazy evaluation
- Full IntelliSense support for VisualStudio
- Supports jQuery
- Supports Windows Script Host
- Binding for Reactive Extensions for JavaScript(RxJS) and IntelliSense Generator
- NuGet install support
- Updated recently (last release Jan 2011)
- Syntax conforms to lambda syntax in C#
Cons
- The linq.js library is a little large.
- If you are already using jQuery or other js library, the most commonly used functionality is probably already available. See especially jQuery's filter, and 'Any' methods.
