UUID v4 uses 122 random bits — the chance of a collision between two UUIDs is astronomically small.

Generated with crypto.getRandomValues — cryptographically secure, never sent to a server.

Frontend tips

⚛️

React list items need unique keys. For dynamically generated items (not from a database), pre-generate UUIDs and attach them as the key prop.

💡

Avoid using array index as key — it causes re-render bugs when items are reordered. A UUID assigned at creation time stays stable through reorders.

🔗

For multi-step forms where each step can add items, generate a UUID when the user clicks "Add item" so each row has a permanent ID from creation.

📋

In vanilla JS, use the UUID as a data attribute: data-id="550e8400-..." to identify DOM elements without a database-backed ID.
