Example brief

A habit tracker needs to keep its data between visits and let a person take it to another device.

An example. Use your own idea next.

Steps

Ask for a object with load and save, and a block for names and keys.
Add Export and Import buttons that use JSON.
Export, change something, then import. Did the data come back exactly?

What you will learn

Store: A small piece of code that is the only place data is read or written. Screens ask it; they never touch storage.
Portable data: Data in a plain format such as JSON that any platform can read, so it can move with the person.
Config: One block holding names, keys and addresses, so moving to a new platform means editing one place.

A sample prompt

A habit tracker. All data goes through a store object with load and save, settings live in one CONFIG block, and there are Export and Import buttons that use JSON. Show a message when import fails.

Write yours first, then compare.
