Question

Is there a present? method in ruby to check if a string is present within an other? I’d want to return as soon as a match is found since I will be checking for multiple substrings. Thanks!

Answer 1

Sorry, found what i was looking for (because of the use of regexp):

index(regexp [, offset]) → fixnum or nil

Returns the index of the
first occurrence of the given substring or pattern (regexp) in str.
Returns nil if not found.

"hello".index('lo')            #=> 3
"hello".index('a')             #=> nil
"hello".index(?e)              #=> 1
"hello".index(/[aeiou]/, -3)   #=> 4

i just used a loop checking if the index is nil
