Sort objects by property names using native Array.sort()
npm install sort-bysort-by 
=====================
A utility to create comparator functions for the native Array.sort() in both node and the browser. Allows for sorting by multiple properties.
Inspired by [this StackOverflow answer][1].
----------
Example
---------
var sortBy = require('sort-by'),
users = [];
users = [{
id: 7,
name: 'Foo',
age: '34',
email: { primary: 'foo@email.com' }
}, {
id: 3,
name: 'Baz',
age: '67',
email: { primary: 'baz@email.com' }
}, {
id: 4,
name: 'Bar',
age: '67',
email: { primary: 'bar@email.com' }
}];
users.sort(sortBy('name', 'age'));
/**
* result:
* [{id: 4, name: 'Bar', age: '67', email: { primary: 'bar@email.com' }},
* {id: 3, name: 'Baz', age: '67', email: { primary: 'baz@email.com' }},
* {id: 7, name: 'Foo', age: '34', email: { primary: 'foo@email.com' }}]
*/
/**
* Use - to reverse the sort order
*/
users.sort(sortBy('-id', 'name'));
/*
* result:
* [{id: 7, name: 'Foo', age: '34', email: { primary: 'foo@email.com' }},
* {id: 4, name: 'Bar', age: '67', email: { primary: 'bar@email.com' }},
* {id: 3, name: 'Baz', age: '67', email: { primary: 'baz@email.com' }}]
*/
/**
* Use . notation to traverse nested properties. See object-path npm module for support.
*/
users.sort(sortBy('age', 'email.primary'));
/*
* result:
* [{id: 7, name: 'Foo', age: '34', email: { primary: 'foo@email.com' }},
* {id: 4, name: 'Bar', age: '67', email: { primary: 'bar@email.com' }},
* {id: 3, name: 'Baz', age: '67', email: { primary: 'baz@email.com' }}]
*/
