--description--
Using regexes like /coding/
, you can look for the pattern coding
in another string.
This is powerful to search single strings, but it's limited to only one pattern. You can search for multiple patterns using the alternation
or OR
operator: |
.
This operator matches patterns either before or after it. For example, if you wanted to match the strings yes
or no
, the regex you want is /yes|no/
.
You can also search for more than just two patterns. You can do this by adding more patterns with more OR
operators separating them, like /yes|no|maybe/
.
