Pattern: Comparing variable with multiple items

Issue: -

Description

This rule checks against comparing a variable with multiple items, where Array#include? could be used instead to avoid code repetition.

Examples

# bad
a = 'a'
foo if a == 'a' || a == 'b' || a == 'c'

# good
a = 'a'
foo if ['a', 'b', 'c'].include?(a)
