FragmentMorphic class final

A grouping node that produces no DOM element.

FragmentMorphic holds a list of children that are inserted directly as siblings into the parent DOM node. It is the Morphic representation of Fragment — a way to group multiple nodes without introducing a wrapper element in the HTML output.

Example

// Fragment in render() — no extra div wrapper in the DOM
Fragment()([
  Span()(['First']),
  Span()(['Second']),
])

Diffing

FragmentMorphic is preserved in the resolved tree so that _patchChildren can diff it correctly against a previous fragment at the same position, updating only the children that changed.
