Extraction of "ruby" double hash * Review

ruby.rb

user_data = [
  {
   
 user: {
        profile: {
            name: 'takeshi'
        }
    }
  },
  {
    user: {
        profile: {
          name: 'tanaka'
        }
    }
  },
  {
    user: {
        profile: {
            name: 'tosiki'
        }
    }
  }
]

In the above code, the individual data exists in the array as a double hash. __ ** I want to put all the user names in order! !! !! ** __

Implementation

ruby.rb

#each method
Unused patterns

puts user_date[0]["user"]["profile"]["name"]
puts user_date[1]["user"]["profile"]["name"]
puts user_date[2]["user"]["profile"]["name"]

ruby.rb

#each method usage pattern

user_date.each do |date|
  puts date [:user][:profile][:name]
end

!important

When multiple hashes overlap, the value of the name key can be displayed by specifying the key that you want to display consecutively from the first "key" of the hash.

result

__ I was able to output just the name brilliantly! !! __

1. If you do not use each method, specify the subscripts one by one and describe the keys consecutively.
2. I was able to concisely specify keys consecutively using each method

takeshi
tanaka
tosiki

** Consideration **

It may be because I'm a beginner that it's hard to see if it's the top code description method, but I converted it to the following code description method ...

user_date = [
  { user: { profile:  { name: "takeshi" }}},
  { user: { profile:  { name: "tanaka" }}},
  { user: { profile:  { name: "tosiki" }}}
]
