Usage

Require nested-values

const nestedValue = require('nested-value');

You can get nested value from an object:

const nestObj =  { a: { b: { c: "i'm here" } } };

const nestedValue = nestedValue(nestObj, 'a.b.c'); //=> "i'm here"
//or
const nestedValue = nestedValue(nestObj, ['a','b','c']); //=> "i'm here"

Or value inside an nested array

const nestArray = [[['a'], { b: 'valueB', c: [{ d: 'valueD' }] }]];
const nestedValue = nestedValue(nestArray, '0.1.c.0.d');
// => "valueD"

You can also pass a callback:

const nestObj =  { a: { b: { c: "i'm here" } } };

const newObject = nestedValue(nestObj, 'a.b.c', function (val){
    return { foo: val }
});
//=> { foo: "i'm here" }
