Discussion on: How to safely access deeply nested object in Javascript

For this purpose I'd recommend using what majority of devs use for this purpose: lodash.

import get from 'lodash/get'

const comments = get(props, 'user.posts[0].comments', [])

This makes code easier for more people to understand. Also, using try ... catch and creation of new function for each iteration might hurt performance in tight loops. lodash implementation is both optimized for performance and has tests for edge cases.
