Use the SolidJS Show primitive for conditional rendering instead of generic ternaries to maintain fine-grained reactivity. It ensures predictable reactive behavior and optimal DOM updates by only evaluating the condition and rendering the matched view without re-rendering the entire component.

Rendering lists in SolidJS is best handled by the For primitive for reference-keyed arrays or the Index primitive for index-keyed arrays. They optimize DOM updates by tracking items without mapping over arrays like React, ensuring high performance across large datasets.

Map-based rendering causes performance issues in SolidJS because it bypasses the compiler's fine-grained reactivity model. It recreates DOM nodes unnecessarily, whereas using SolidJS control-flow primitives like Show and For ensures predictable updates and preserves DOM optimizations.

Yes, you can use the Dynamic primitive for rendering dynamic components and the Portal primitive for portal-driven UI in SolidJS 1.x and 2.x projects. These primitives integrate natively with the SolidJS JSX compilation model to maintain robust templates and predictable reactivity.

Switch and Match should be used over Show when you have multiple mutually exclusive conditions to evaluate in SolidJS. This control-flow primitive pattern provides a cleaner structure for complex conditional routing compared to nested Show components.

Suspense boundaries in SolidJS work by catching asynchronous resource loading and displaying fallback content until resolution. Applying this Suspense primitive within your JSX patterns ensures smooth UI transitions during data fetching without blocking the main thread.
