Like extend but only copies missing properties/values to the target object.


Install with npm:

$ npm install --save object.defaults

Install with bower

$ bower install object.defaults --save


var defaults = require('object.defaults');

var obj = {a: 'c'};
defaults(obj, {a: 'bbb', d: 'c'});
//=> {a: 'c', d: 'c'}

Or immutable defaulting:

var defaults = require('object.defaults/immutable');
var obj = {a: 'c'};
var defaulted = defaults(obj, {a: 'bbb', d: 'c'});
console.log(obj !== defaulted);
//=> true
