Step 6: LocalStorage Syncer

6. LocalStorage Syncer

Sync local memory state tables to browser localStorage caches.

Detailed Implementation Steps:

Implement a sync function that serializes the state tasks array using JSON.stringify() and saves it to browser localStorage: localStorage.setItem('voidx_tasks', data). Invoke this function inside all mutation handlers (add, toggle, delete).

Modify your initial page load script: check if tasks exist in localStorage. If they do, parse them using JSON.parse() and load them into your state array before executing the initial render.

Verification Checklist:

1. Create several task items and refresh the browser; confirm the list remains populated.
