#3153 — How can I do the dictionary?

I am a newbie but I'm familial with C#.
I can't find any dictionary class in Ruby.
I need to do like Dictionary<key, List<string>>

Can I do that in Ruby? If yes, how?
Big thanks!

I think what you seek is Hash.

my_hash = {
  'fruits'  => ['apple', 'pear'],
  'cars'    => ['VW', 'BMW', 'Ford']
}

p my_hash['cars']

--output:--
["VW", "BMW", "Ford"]


my_hash['rocks'] = ['granite', 'quartzite']
p my_hash

--output:--
{"fruits"=>["apple", "pear"], "cars"=>["VW", "BMW", "Ford"], 
"rocks"=>["granite", "quartzite"]}
