Tips
• Use the global (g) flag to find all matches, not just the first one
• Enable ignore case (i) for case-insensitive matching
• Multiline (m) makes ^ and $ match start/end of each line
• Dotall (s) makes . match newlines too
• Use parentheses () to create capture groups
• Escape special characters with backslash: \\. \\* \\+
