How to write a switch statement in Ruby

In Ruby, a case statement is used as a switch statement to compare a value against multiple conditions. Here’s the syntax and an example:

Syntax:

case variable
when value1
# Code to execute if variable == value1
when value2
# Code to execute if variable == value2
else
# Code to execute if no matches
end

Example:

day = “Monday”

case day
when “Monday”
puts “Start of the workweek!”
when “Friday”
puts “Almost the weekend!”
else
puts “Just another day.”
end

Output:

Start of the workweek!

Key Points:

Use case to specify the variable being compared.

Use when for each condition.

Use else for a default case if no conditions match.
