Objectify 

This node library allows you to set, get or check for the predicate of a
deeply nested objects.

It lets you avoid patterns such as:
``javascript
if (myObj.options && myObj.options.site && myObj.options.site.url) {
// do something with myObj.options.site.url
}
`

And it helps you avoid the popular undefined is not a function error.

Examples

`javascript
var objectify = require('objectify');

var src = {};

`

Check for the existence of a nested attribute:

`javascript
if (objectify(src).isSet('a.very.deeply.nested.attr')) {
// true or false
// do something with the nested attr here
console.log(src.a.very.deeply.nested.attr);
}

`

Getting a long nested attribute:

`javascript

src = {a: {very: {deeply: {nested: { attr: 1 }}}}};

objectify(src).get('a.very.deeply.nested.attr'); // returns 1

objectify(src).get('a.non.existant.attr'); // returns undefined

`

Setting a deep nested attribute:

`javascript

objectify(src).set('a.different.nested.attribute', 2); // returns 2

console.log(src.a.different.nested.attribute) // 2
