🚀 Rendering 100k+ items in React? Here’s what actually works.
Large lists can easily kill performance if handled the wrong way. This is how I approach it in real projects:
• Virtualization Render only what’s visible using libraries like react-window. Massive win.
• Memoization React.memo, useMemo, and useCallback help avoid unnecessary re-renders.
• Pagination / Infinite Scroll If users can’t see it yet, don’t render it yet.
• Lightweight DOM Shallow, simple components render and update much faster.
Rule of thumb: If you’re rendering 100k items at once, the issue is usually architectural, not React itself.
Always curious how others tackle large-scale UI performance.
