The Extract Method refactoring allows you to extract a specified code fragment into its own method.

To extract a method:

Example

Before

class Hello
    def greet
        name = "JetBrains"
        puts "Hello from #{name}"
    end
end

After

class Hello
    def greet
        name = "JetBrains"
        puts get_greeting(name)
    end
 
    private
 
    def get_greeting(name)
        "Hello from #{name}"
    end
end
