JarCastingsort-keys 
Sort the keys of an object
Useful to get a deterministically ordered object, as the order of keys can vary between engines.

$ npm install sort-keys
Usage
const sortKeys = require('sort-keys');
sortKeys({c: 0, a: 0, b: 0});
//=> {a: 0, b: 0, c: 0}
sortKeys({b: {b: 0, a: 0}, a: 0}, {deep: true});
//=> {a: 0, b: {a: 0, b: 0}}
sortKeys({b: [{b: 0, a: 0}], a: 0}, {deep: true});
//=> {a: 0, b: [{a: 0, b: 0}]}
sortKeys({c: 0, a: 0, b: 0}, {
compare: (a, b) => -a.localeCompare(b)
});
//=> {c: 0, b: 0, a: 0}
