import { getProp } from '@elementary/proper';

const dumas = {
  object: {
    deepObject: {
      musketeers: 3,
    },
  },
};

// With Map
compose(
  map(map(getProp('musketeers'))),
  map(getProp('deepObject')),
  getProp('object'),
)(dumas)
  .get()
  .get()
  .get(); //=> 3

// With Chain
compose(
  chain(getProp('musketeers')),
  chain(getProp('deepObject')),
  chain(getProp('object')),
)(Maybe(dumas)).get(); //=> 3

High Level API

import { access } from '@elementary/proper';

const dumas = {
  object: {
    deepObject: {
      musketeers: 3,
    },
  },
};

access('object.deepObject.musketeers')(dumas); //=> 3
access('object.deepObject.samurais')(dumas); //=> null
access('object.noObject.musketeers')(dumas); //=> null
