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:

$ npm install --save unset-value

Usage

var unset = require('unset-value'); unset(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

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

Returns true when a property is deleted

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.

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

delete nested values

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

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