unset-value
Delete nested properties from an object using dot notation.
Install
Install with npm:
$ npm install --save unset-value
Usage
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
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.'
