I just use lodash get when I access object properties

`get` will destroy type inference, there's no workaround. Your output types are always `any`. The new optional chaining fixes that problem, giving you the same terseness as `get`

In lodash's defense, there is a @types package for it, which has a typed _.get. However, in my experience, the lodash typings are really difficult to use correctly.

Definitely will be replacing usage of _.get with optional chaining soon.

https://www.npmjs.com/package/typesafe-get works pretty good

right but the person I was responding to isn't using typescript, they were just considering it. For a non typescript user lodash get would be fine.

TS 3.7 obviates the need for using `lodash.get` or `just-safe-get`, but it does so in a way that preserves the type of your object
