How to start learning assembly language in 2021?

Question

assembler

I want to learn how to write the most optimized code in order to understand how all language constructs work at a low level. I found the book Kalashnikov O. - Assembler is simple. Learning to program, 2011. I didn't find something newer that I would advise on the forums. This book covers both 16 and 32 bit systems and cannot even run the example files. I would like some book, a modern book on assembler for 64-bit systems. What version of assembler is better to choose to start with?
