Having trouble learning rgss

じ☆ve冰风

Hello! I'm not quite sure this is the right place to ask but I'd assume so. I'm having trouble learning ruby scripting. I've tried to look for sites or videos, but I can't find anything. Specifically, I can't find the definition to these " reserved words ". This is the list of words I found while searching which go under this name:

BEGIN    class    ensure   nil      self     when
END      def      false    not      super    while
alias    defined? for      or       then     yield
and      do       if       redo     true
begin    else     in       rescue   undef
break    elsif    module   retry    unless
case     end      next     return   until

I've found the definition of " class " and " def ", but nothing on the other words. If someone could explain to me what they do and an example of what they'd be used for or a link with the information I desire it would be greatly appreciated. I don't want to use other people's scripts as I'd rather be able to make them myself.

Also, bonus question. Does it matter what I put after " def "? I've seen people either use " initialize " or " main " and I don't know if that means anything or not. Thank you for reading!


(I have no programming experience, if that matters)
