Rubyにおけるハッシュとシンボルのまとめ

ハッシュとシンボルの書き方まとめ

 学習していく中で、ハッシュの実装方法の違いが出てきたためまとめます。

test.rb

# キーが文字列の書き方
test{"subject" => "Math" , "score" => 60}
# キーがシンボルの書き方
test1{:subject => "Math" , :score => 60}
# キーがシンボルの書き方(省略系)
test2{subject: "Math" , score: 60}

# それぞれの出力方法
puts test["subject"]
puts test1[:subject]
puts test2[:subject]

実行すると、全て同じ値が出力されました。
学習するたびに、投稿していこうと思います。。。
