depends on your definition of "main" language. lite-C is the newest, best, least restricting, and now only updated language, so i'd call it main.
C-script at the moment is more popular because most people think lite-C might be hard to learn.
there is no point in learning C-script before lite-C if you already have the means to learn either.
and either way, AlbertoT answered CharlieNutSak14's question regarding a "non-programmers" way, so "no" is not the right answer.
