It's not a question, just a feeling
I'll probably never get in touch with the languages in this book (but who knows). I never grew any interest on them, maybe because I don't even know what they're all about, or maybe because their names all sound like foreign brand washing machine powder. But I'm open to almost anything in programming.
It seems to be a great guide to understand the "why" being each language, and their pros and cons. At least I like what I've read from the
publisher's page, and the book cover is awesome
