> 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.'
|
|
```
