I am new to ruby, I am trying to write a method that checks if the word includes "hello" case insensitive e.g "HelLO" would still be true.

I think the easiest approach is to downcase both string and do the comparing. Like this:

'HellO'.downcase.include?('hello')
# true

I can think of two approaches:

1. downcase before comparing

   str = "HelLO"
   
   str.downcase.include?('hello')
   #=> true
   

2. use case-insensitive regular rexpression

   str = "HelLO"
   
   str.match?(/hello/i)
   #=> true
