Hello,

How can I write a logical or operator for two values?

I've tried `if [type] == "test-request" || [type] == "test1-request"` but this gives me a syntax error.  
I want it to work on how a logical OR operator works. If type value matches either one then true else false.

sorry for the trouble. Got confused going through multiple documents.

Ruby logical operator on [tutorialspoint](https://www.tutorialspoint.com/ruby/ruby_operators.htm) gives another description of how "or" is used. so I wasn't sure if that works.

"Called Logical OR Operator. If any of the two operands are non zero, then the condition becomes true."
