【Ruby】%wで配列を作る

Last updated at Posted at 2021-11-02

環境

Ruby 3.0.2

配列の書き方

%記法は、要素が文字列リテラルかシンボルリテラルの場合に限り配列表現ができる。

array1、array2ともに同じ結果になる

array1 = ['apple', 'grape', 'peach']
array2 = %w(apple grape peach)

#=> ["apple", "grape", "peach"]

丸カッコ以外でもいける

%w{...}
%w[...]
%w|...|
小ネタ

wはwordから来ているらしい
