Regex is a powerful sequence of characters that forms a search pattern:
- Validation: Check if an input is a valid email, password (strength), or URL.
- Search & Replace: Find specific patterns in large documents and swap them instantly.
- Flags: Use
g(global) to find all matches, ori(insensitive) to ignore uppercase/lowercase.
What do the slashes / / mean? +
In programming, Regex patterns are usually wrapped in forward slashes. Anything after the second slash (like 'g' or 'i') is called a "flag" that changes how the search works.
