I want to get the static part of a RegExp string, which 100% guaranteed to not have a regex-specific characters, except the grouping parentheses ()
.
for instance, this regex /path/config-(.+)/.js/
has a static part /path/config-
until the character ‘.’
use cases:
I want to search for all matched entries inside a folder that have too many files and subfolders.
so, it is a bit faster to start searching from the basic path /path
that doesn’t needed to be matched against, instead of starting from the root directory.
