Ruby Silver勉強の参考に

Posted at

先日Ruby Silverの試験に合格できたので勉強時に暗記した内容の一部です。

破壊的メソッド

concat
pop
shift
unshift
push
delete_if
clear

別名など

delete_if　→　reject! 
update　→　merge!
find_all　→ select
collect　→ map
member?　→　include?
select → find_all
find → detect

本当に一部ですが覚えておくと試験で4~6点くらい正解できると思います！
頑張ってください！
