sort-object
Sort the keys in an object.
Install
Install with npm:
$ npm i sort-object --save

var sortObj = require('sort-object');
By default, the keys on an object will be sorted in ascending order:
sortObj({a: 1, c: 2, b: 3});
//=> {a: 1, b: 3, c: 2}
The second param can be an object of options
OR an array of keys
:
object
sortObj({a: 1, c: 2, b: 3}, {keys: ['a', 'b']});
//=> {a: 1, b: 3}
array
sortObj({a: 1, c: 2, b: 3}, ['a', 'c']);
//=> {a: 1, c: 2}
