-
- > Delete nested properties from an object using dot notation.
-
- ## Install
-
- Install with [npm](https://www.npmjs.com/):
-
- ```sh
- $ npm install --save unset-value
- ```
-
- ## Usage
-
- ```js
- var unset = require('unset-value');
-
- var obj = {a: {b: {c: 'd', e: 'f'}}};
- unset(obj, 'a.b.c');
- console.log(obj);
- //=> {a: {b: {e: 'f'}}};
- ```
-
- ## Examples
-
- ### Updates the object when a property is deleted
-
- ```js
- var obj = {a: 'b'};
- unset(obj, 'a');
- console.log(obj);
- //=> {}
- ```
-
- ### Returns true when a property is deleted
-
- ```js
- unset({a: 'b'}, 'a') // true
- ```
-
- ### Returns `true` when a property does not exist
-
- This is consistent with `delete` behavior in that it does not
- throw when a property does not exist.
-
- ```js
- unset({a: {b: {c: 'd'}}}, 'd') // true
- ```
-
- ### delete nested values
-
- ```js
- var one = {a: {b: {c: 'd'}}};
- unset(one, 'a.b');
- console.log(one);
- //=> {a: {}}
-
- var two = {a: {b: {c: 'd'}}};
- unset(two, 'a.b.c');
- console.log(two);
- //=> {a: {b: {}}}
-
- var three = {a: {b: {c: 'd', e: 'f'}}};
- unset(three, 'a.b.c');
- console.log(three);
- //=> {a: {b: {e: 'f'}}}
- ```
-
- ### throws on invalid args
-
- ```js
- unset();
- // 'expected an object.'
- ```
