I’ve skimmed these and I’m not convinced they’re worth the purchase. Every time there’s a Packt bundle it’s a mixed bag. I don’t think these are great for a beginner because of the usual Packt concerns and I don’t think they’re great for an expert because of the usual Packt concerns. For the midtier unless you need these right now and have no other resources, it’s a better bet to wait for a similar bundle, even in other languages, from Manning or O’Reilly.
