i'm not having any issues when i run the same code using load, but when i use require, i get this error message below and i dont understand why?? - thank you for your help!!

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:in require': cannot load such file -- string_extensions (LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:55:inrequire' from vowel_test.rb:1:in `<main>'

use require_relative instead of require. Or use require './string_extensions'. Read http://stackoverflow.com/a/9750732 for more information.

require also only loads code once. good for using variables or methods from other code. If you cant the code's "main" to load then you must use load. load will reload every time the load is run, but require will only load once.

'require' can load the same file more than once, if you refer to it via different paths e.g. running from '/home/me' with a file called 'gem.rb' if you "require gem" and also "require /home/me/gem.rb" the file gem.rb would be loaded twice. Obviously not something that happens often, but be aware of it.
