简化if equals（==）语句

Question

如何简化以下if语句以删除重复？

if user.name == "john" && user.age > 10 or user.name == "wendy" && user.age > 10 or user.name == "mary" && user.age > 10

谢谢！

Answer 1

使用Array#include?

if ['john', 'wendy', 'mary'].include?(user.name) && user.age > 10

Answer 2

require 'set'

target_names = Set.new ["john", "wendy", "mary"]

if target_names.include? user.name and user.age > 10  ...
