Comment cela fonctionne

The tester builds a JavaScript regular expression from your pattern and selected flags, then scans the text and lists every match with its position.

Conseils

  • Turn on the global flag to capture every match instead of just the first one.
  • Case-insensitive matching is useful for email, tags, and user-entered text.
  • Invalid syntax is reported immediately so you can fix the pattern quickly.
