JSX Traits

JSX Traits composes behavior directly on intrinsic elements through an ordered pipeline of plain functions. Each trait receives the previous value and its own namespaced props, then returns the value passed to the next trait.

<traits.button
  of={[{ press }, { analytics }]}
  press:onPress={save}
  analytics:event="save"
>
  Save
</traits.button>

Array order is execution order. JSX namespaces isolate each trait's options, and TypeScript checks the handoff between adjacent traits.
