Arguments

object: The object you want to use as source for the update.

path: Array of property names that lead to the value to update.

callback: Function you want to perform on the value in path.

Returns

new Object: if path is a valid set of properties.

false: if path is not a valid set of properties.

Use

Terminal

npm i deep-update-object --save

In your project

const deepUpdateObject = require('deep-update-object');

const object_1 = {a: 1, b: {c: 3, d: { e: 5}}};
const object_2 = deepUpdateObject(object_1, ['b','d','e'], val => val + 5);

// object_1 = {a: 1, b: {c: 3, d: { e: 5}}}
// object_2 = {a: 1, b: {c: 3, d: { e: 10}}}

// Returns false when called with wrong path
const object_3 = deepUpdateObject(object_1, ['x','y','z'], val => val + 5);
// object_1 = {a: 1, b: {c: 3, d: { e: 5}}};
// object_3 = false
