Week 2/40 — Idea Log & Randomizer

Tech stack (this week)

• Plain HTML + CSS + JavaScript

• Browser storage: localStorage

• Hosting: GitHub Pages

New topic: persistence without a backend (localStorage).

Why this week?

I wanted a small step up from static: something interactive that remembers data. Still simple, still shippable.

What I shipped

A tiny app where I can add ideas (title + description), see them in a list, and pick a random one — stored in localStorage so it survives refreshes.

Demo (copy/paste):

The One Feature Rule

One feature: CRUD-ish idea list + random pick, persisted in browser.
Not doing: accounts, databases, frameworks.

What I learned

Persistence is a product feature. Even “just localStorage” makes an app feel real.

Follow along (code it yourself)

1. Build a form → push idea objects into an array.

2. Save array JSON to localStorage.

3. On load: read JSON → render list.

4. Add “Random” button: pick an index and display it.
