Usage

.get(obj, path)

• @param {Object} object
• @param {String} path
• @return {Object} value or undefined

Retrieve the value in an object given a string path.

var obj = {
    prop1: {
        arr: ['a', 'b', 'c']
      , str: 'Hello'
    }
  , prop2: {
        arr: [ { nested: 'Universe' } ]
      , str: 'Hello again!'
    }
};

The following would be the results.

var properties = require('tea-properties');
properties.get(obj, 'prop1.str'); // Hello
properties.get(obj, 'prop1.att[2]'); // b
properties.get(obj, 'prop2.arr[0].nested'); // Universe

.set(path, value, object)

• @param {Object} object
• @param {String} path
• @param {Mixed} value

Define the value in an object at a given string path.

var obj = {
    prop1: {
        arr: ['a', 'b', 'c']
      , str: 'Hello'
    }
  , prop2: {
        arr: [ { nested: 'Universe' } ]
      , str: 'Hello again!'
    }
};

The following would be acceptable.

var properties = require('tea-properties');
properties.set(obj, 'prop1.str', 'Hello Universe!');
properties.set(obj, 'prop1.arr[2]', 'B');
properties.set(obj, 'prop2.arr[0].nested.value', { hello: 'universe' });
