What is a switch statement in Ruby?

In Ruby, a switch statement is implemented using the case keyword, allowing you to execute different code based on the value of a variable.

Can you give me an example of how to use it?

Sure! Here's a simple example:

value = 2
case value
when 1
  puts 'One'
when 2
  puts 'Two'
when 3
  puts 'Three'
else
  puts 'Not a valid number'
end

What happens if none of the cases match?

If none of the cases match, the code in the else block will be executed, if it exists. Otherwise, nothing happens.

Are there any limitations to using switch statements in Ruby?

Yes, switch statements in Ruby can only evaluate a single expression, and they don't support fall-through behavior like in some other languages.
