unset-value - npm

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 ❤️ and support.

Install with npm:

$ npm install --save unset-value

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

• 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.

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

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

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

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'}}}

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