Stylus regex to JavaScript regex

JavaScript regex to Stylus regex

Differences

• \ must be escaped using CSS syntax (\\). It's escaped automatically if you're using the "Applies to" field in the stylus editor.
• / no need to escape (but you can \\/ 🤯).
• You must match the entirety of the URL (no need to add ^ and $).
• That said, JavaScript regex is a valid Stylus regex.
