Question

I’m looking to extract a subsection of a javascript array of objects based on a certain condition, e.g:

object.property == 2

I know that I could look through and build a new array from the ones that match, but I was wondering whether there was a shorthand for this.

You can use grep().

var arr = [ 1, 2, 3 ];
var subset = $.grep(arr,function(n,i){ return n >= 2 });
// subset = [2, 3]
