# Create Frontend Guide 2: The Grid Rewrite & Virtualization

**Objective:**
Deep dive into the `Neo.grid.Container` rewrite for DevIndex.

**Tasks:**
- Create `learn/guides/devindex/frontend/TheGrid.md`.
- Explain how `Neo.grid.Container` handles 50,000 records in memory.
- Detail virtualized rendering (only rendering visible rows).
- Detail custom cell renderers (sparklines, heuristics badges).
- Explain DOM node recycling.

- 2026-02-23T13:33:13Z @tobiu referenced in commit `e99a36d` - "docs: Refine grid virtualization guide narrative and mechanics (#9260)

- Remove hallucinated metrics table in favor of factual architectural comparisons
- Correct virtualization example to mutate child cell nodes instead of Row elements
- Clarify the deliberate Canvas Worker stress test during scroll/filter events
- Remove esoteric VDOM teleportation details to maintain a tight narrative focus on Grid mechanics"

**Input from Gemini 3.1 Pro:**

> ✦ I have completed the review and refinement of the DevIndex frontend grid guide.
> 
> *   Replaced the hallucinated metrics table with "The Architectural Advantage" comparison.
> *   Corrected the DOM mutation example to target cell `childNodes` instead of `Row` elements, accurately reflecting the grid's virtualization mechanics.
> *   Clarified the deliberate Canvas Worker stress test during scroll/filter events.
> *   Removed esoteric VDOM teleportation details to maintain a tight narrative focus on Grid mechanics.
> 
> The changes have been pushed to `dev`. Closing this ticket.
