# regex
There are 2 ways to do regex:
a) using the native module called `regex`
b) using an exteranl module called `pcre`, which wraps the C library pcre.
1. using the native module called `regex`.
2. using an external module called `pcre`, which wraps the C library pcre.
> [!NOTE]
> You need to first do: `v install pcre`, for the `pcre` module to work.
