Regex Tester & Validator

This JavaScript regular expression is designed to parse Bible references for reading accountability tracking. It uses named capturing groups to extract the book name, the starting chapter (`from`), and an optional ending chapter (`to`). It is ideal for parsing simple strings like "John 1" or "Genesis 1-3". However, note that the `\S+` pattern assumes the book name contains no spaces, which may require adjustments for books like "1 John".
