Assuming this is an example for others to quickly learn from, the abstractions built here only make it harder to understand.
- Response json is hidden behind 2-3 layers.
- Storage actions are hidden and it's not clear which storage is used at quick glance.
- JavaScript is written in a highly abstract manner, it would be easier if the steps are numbered and run from separate functions & again too much abstraction for learning purposes.
