Delete nested properties from an object using dot notation.


Install with npm:

$ npm install --save unset-value


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

var obj = {a: {b: {c: 'd', e: 'f'}}};
unset(obj, 'a.b.c');
//=> {a: {b: {e: 'f'}}};


Updates the object when a property is deleted

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

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');
//=> {a: {}}

var two = {a: {b: {c: 'd'}}};
unset(two, 'a.b.c');
//=> {a: {b: {}}}

var three = {a: {b: {c: 'd', e: 'f'}}};
unset(three, 'a.b.c');
//=> {a: {b: {e: 'f'}}}

throws on invalid args

// 'expected an object.'
