The power of Regex
Regular Expressions (Regex) are sequences of characters that define a search pattern. They are indispensable for find-and-replace, data validation, and advanced text processing.
Common Flags Guide
- **g (Global)**: Don't stop at first match; find all occurrences. - **i (Case-insensitive)**: Ignore case when matching. - **m (Multiline)**: Treat beginning/end characters (`^` and `$`) as working across multiple lines.
