Adobe experience manager and JS

Hello guys,

I have an interview for a company that pays really good money, and I think I can get the gig, it is basically front end under Adobe Experience Manager.
I have worked with AEM a little bit in the past, but they have changed the version and the stack under where it runs, from Java to JS,
so, with that being said, does anybody here know where can I pick up a good course on AEM?
