Hello community ! 
Could you suggest me any pro/hard Javascript-Books, please ?
Please, i honestly need your help.
Thank You in advance !
Professional JavaScript for Web Developers is a very comprehensive book (24 chapters) - covering everything from syntax to very advanced topics. I haven’t finished reading it because it is very thorough and I ran out of time.
Thank you sir ! Your opinion is very important for me. Could you inform me, which is/are the Author(s) of this Book please?
Nicholas C. Zakas ?
Yes, i am interested about a comprehensive book which covers almost everything. Not for a book which covers the Basics.
Yes he is the author of that book.
A bit late on the reply, but here’s an excellent curated treasure trove of books for people who love code.
