Question

I am trying to learn Ruby and I have the following code

 a[0]={ :artist => 'Green Day',
                          :name => 'Song1',
                                                   :bitrate => 192 }
 a[1]={ :artist => 'U2', :name => 'Song2' }
 a[2]={:artist => 'Metallica', :name => 'Battery' }

My question is how do I find in such an array all the songs by Metallica, for example? Thank you! 🙂

Edit: Ok, another newbie question? How can I find the songs that contain a certain sequence in their titles?

I tried:

a.find { |x| x[:song].include? 'Song' }

but it returns an error.

Answer 1

a.select { |song| song[:artist] == 'Metallica' }

and for your second question

a.select { |song| song[:name].include? 'Song' }
