Sort Objects

README.md

Objects Sorter:

Sort objects by property name. It detects property type such as number, string, and date and sort them properly.

Usage

var models = [
      {name: "john", level: 42, dob: "01/12/1940"},
      {name: "joe", level: 12, dob: "01/12/1941"},
      {name: "amber", level: 50, dob: "02/2/2001"}
    ];

// cache the sort fn, and sort by name
var sortFnCache = sortProp('name');
models.sort(sortFnCache);
