USAGE

With object:

const set = require('set-new');
const source = { some: { nested: 'object' };

const result = set(source, ['some', 'nested'], 'changed');

source.some.nested === 'object'; // true
result.some.nested === 'changed'; // true

const another = set(result, 'some.nested', 'another');

result.some.nested === 'changed'; // true
another.some.nested === 'another'; // true

With array:

const set = require('set-new');
const source = ['some', ['nested', ['array']]];

const result = set(source, [1, 1], 'changed');

source[1][1] === 'object'; // true
result[1][1] === 'changed'; // true

const another = set(result, '1.1', 'another');

result[1][1] === 'changed'; // true
another[1][1] === 'another'; // true
