Hello y’all, in this post I would be writing on how intuitive case statements are in Ruby. Ruby powers some popular websites in the world.
And do you know that one of the languages powering GitHub is Ruby? Ok, let me not sidetrack. Let us get into the use of the
case statement in Ruby.
A run-down of what the code above does
gets.chompmethod collects input from a user and strips off the new-line at the end of the input.
casestatement selects the variable that the
whenstatement uses to compare values.
- If any of the
whenstatements matches the value of the
foodvariable, it executes the code within it.
- So let us say you input
riceas food, the case statement would print “I ate rice”.
casestatement must end with the
The case statement above is quite limiting. What happens when a user inputs a value that isn’t handled by the
when statement? From the code above nothing would be logged out.
The good thing about the
case statement in Ruby is that it supports the use of the
else statement is used within the case statement it handles all the values that aren’t handled by the
when statement. The example below explains further:
When a user inputs a value that isn’t handled by the
when statement the code within the
else statement is executed.
And finally, the
when statement allows you to compare a group of values against the
The code below is an example:
when statement is separated with a comma, it checks to see if any of the
when values matches the value of the
So in this case, if the user inputs
plantain, “You ate beans or plantain would be printed”
Thanks for reading through. Hope you learnt a little bit about Ruby and its intuitiveness😋
