# --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/`.
|
|
