String matchAll()

String.prototype.matchAll() returns an iterator of every match for a global regular expression, including capturing groups. It is often cleaner than a manual exec loop.

Use cases

  • Extracting repeated patterns

    Pull prices, links, tags, or identifiers from a text block while preserving capture groups.

  • Building derived lists

    Iterate over all matches to create result rows, summaries, or highlighted tokens.

Cautions

  • matchAll requires a global regular expression, so remember the g flag or it will throw.
  • Complex regular expressions can still be hard to debug, so keep the pattern readable and well tested.

Accessibility

  • When extracted text becomes a list or summary in the UI, present the results with clear headings and counts rather than dumping raw output.
