Ruby .detect alternative

I am looking for an alternative that would solve the following issue:

with .detect if I am looking for stringvalue and the value given is 132stringvalue, it will still return true. I need an alternative that will be matching everything from the beginning of the string. Any suggestions aside from regex?

Solution 
  • [1] pry(main)> %w[foo 456foo bar 123bar].detect {|e| e.to_i > 0}
=> "456foo"
[2] pry(main)> %w[foo 456foo bar 123bar].detect {|e| e.start_with?('123')}                   
=> "123bar"
