Case statement with multiple values in each "when" block

🚘 Case Statement with Multiple Values in Each 'When' Block: A Handy Guide

Are you stuck with a case statement conundrum involving multiple values in each 'when' block? Fear not! We're here to rescue you from this coding dilemma with some easy solutions and nifty tips.

The Problem: Failed Code and Ambiguous Situations 😱

Your failed code attempt looked like this:

case car
  when ['honda', 'acura'].include?(car)
    # code
  when 'toyota' || 'lexus'
    # code
end

You've got 4 or 5 different 'when' situations, all triggered by around 50 possible values of car. But your code is not working as expected. So, is there a way to work this out using 'case' blocks or should you resort to a massive 'if' block?

The Solution: Mastering the Art of Case Statements 🎨

Fortunately, there is a way to achieve what you desire using case statements. Let's dive into a couple of solutions that will streamline your code and make it more readable and maintainable.

Solution 1: Using Ranges for Multiple Values 🌟

If you have a range of values that should trigger the same block of code, you can utilize the power of ranges. Here's an example:

case car
  when 'honda', 'acura'
    # code
  when 'toyota', 'lexus'
    # code
  when 'subaru'..'volvo'
    # code
  else
    # default code
end

By listing each value separately, you can easily group multiple values within a single 'when' block. And if you have a continuous range of values, you can utilize the .. operator to cover all the values in between.

Solution 2: Leveraging Conditionals within 'When' Blocks 🤓

Another approach is to use conditionals within 'when' blocks, which can handle more complex scenarios. Here's an example:

case car
  when ->(c) { ['honda', 'acura'].include?(c) }
    # code
  when ->(c) { c == 'toyota' || c == 'lexus' }
    # code
end

By leveraging lambdas or Procs with conditionals, you can conveniently check multiple conditions within a 'when' block. This allows for greater flexibility and scalability.

Embrace the Elegant Simplicity ✨

With these solutions up your sleeve, you can elegantly handle multiple values within 'when' blocks, making your code cleaner and more maintainable. Say goodbye to confusing if statements or clunky workarounds!

So, what are you waiting for? Give these solutions a try and see your code come to life!
