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.
