Can anyone suggest me best Ruby on Rails 5 book?
If you want to check other books, here you will get best ruby on rails 5 books.
But the book is also well worth buying for reference.
I also found Rails: Novice to Ninja quite good - https://www.sitepoint.com/premium/books/rails-novice-to-ninja
Also, check packt publishing and their free ebooks - https://www.packtpub.com/packt/offers/free-learning - they covers many different languages.
No problem, Chris has release a great series on the site for beginning rails. It’s even on YouTube.
