JavaScript MatchAll Capture Groups Sequence

Inputs: [runtime], [input string], [regular expression]. Explain String.matchAll results using a regex with named capture groups and the global flag. Materialize the iterator, show match text, index and groups separately, and include no-match and optional-group cases. Do not confuse the iterator with an array or silently add unsupported regex syntax. Produce a 12-second highlight animation linking each matched span to its capture record. Adapt the presentation to [audience] and [tone]. End with a concrete check of the defining task detail against the inputs.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
