unset-value

Delete nested properties from an object using dot notation.

Please consider following this project's author, Jon Schlinkert, and consider starring the project to show your :heart: and support.

Install

Install with npm:

1$ npm install --save unset-value

Usage

1var unset = require('unset-value');
2unset(obj, prop);

Params

• obj {object}: The object to unset prop on
• prop {string | string[]}: The property to unset. Dot-notation may be used or an array of nested properties.

Examples

Updates the object when a property is deleted

1var obj = {a: 'b'};
2unset(obj, 'a');
3console.log(obj);
4//=> {}

Returns true when a property is deleted

1unset({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.

1unset({a: {b: {c: 'd'}}}, 'd') // true

delete nested values

1var one = {a: {b: {c: 'd'}}};
2unset(one, 'a.b');
3console.log(one);
4//=> {a: {}}
5
6var two = {a: {b: {c: 'd'}}};
7unset(two, ['a', 'b', 'c']);
8console.log(two);
9//=> {a: {b: {}}}
10
11var three = {a: {b: {c: 'd', e: 'f'}}};
12unset(three, 'a.b.c');
13console.log(three);
14//=> {a: {b: {e: 'f'}}}

throws on invalid args

1unset();
2// 'expected an object.'
