Ruby: Case vs If

What's the difference between using case and if statements in Ruby?

In Ruby, 'case' is used for multiple conditions based on a single variable, while 'if' is for evaluating boolean expressions.

Can you give me an example of both?

Sure! For 'if':

if x > 10
  puts 'Greater than 10'
end

For 'case':

case x
when 1
  puts 'One'
when 2
  puts 'Two'
else
  puts 'Other'
end

When should I use case instead of if?

Use 'case' when you have multiple conditions to check against a single variable, as it can be cleaner and more readable.

Are there performance differences between the two?

Generally, the performance difference is negligible for most applications. Focus on readability and maintainability.
