Sift.js: mongodb inspired array filting

Re:Sift.js: mongodb inspired array filting by phzbOx on Tuesday January 03, 2012 @03:29PM (#3421174)

Can someone explain me why is it useful? I.e. why not using underscore or whatever library provides map and filter?

Thanks for the feedback. I'll add a few use-cases / examples to the project page.

Here are a few good examples which use sift:

- Realtime API library: https://github.com/crcn/guava

- Simple database written in node.js: https://github.com/crcn/gumbo. I use this primarily in command line utilities, and other applications where mongodb seems a bit over the top.

Underscore is certainly a better alternative in many cases, but the goal for sift is to provide control over filtering collections with one query versus manipulating them.

It does remind me of an elaboration on map + reduce + filter. Guess I need to finish reading SICP too.
