find a specific word in a string, case intensive - ruby

Question

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 can think of two approaches:

downcase before comparing

str = "HelLO"

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

use case-insensitive regular rexpression

str = "HelLO"

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

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

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