Most of the books are meant to be consumed in parts. This book explicitly mentions "Segue from previous chapter" for most chapters indicating what key concepts are continued in exploring/building new ones. Also, I believe any reader on HN can make sense quickly of the basic definitions needed to understand a concept in isolation. However, mathematics is especially known to require continuous dedication for years to attain any sort of mastery.
