REGEX_Match_a_Literal_String_with_Different_Possibilities.js

/*
Match a Literal String with Different Possibilities
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/.
