# Hints
|
||
|
|
|
||
|
|
## General
|
||
|
|
|
||
|
|
- Read about the [`Access` behaviour][access-behaviour] in the documentation.
|
||
|
|
|
||
|
|
## 1. Extract data from a nested map structure
|
||
|
|
|
||
|
|
- First tokenize the string path to a usable state. You can make use of [`String` module functions][string-module].
|
||
|
|
- Write a recursive function to traverse the nested-map structure to retrieve the value or return `nil`.
|
||
|
|
|
||
|
|
## 2. Refactor using included functions
|
||
|
|
|
||
|
|
- Read through the various [`Kernel` module functions][kernel-module], to find one that might shorten/simplify your approach.
