Possible disadvantages

    While the text is clear and the code examples are helpful, the book could benefit from more visual aids like diagrams and illustrations to explain complex concepts.
  • Assumes Some Prior Knowledge
    Although it's aimed at beginners, the book sometimes assumes that readers have some prior programming experience, which can make it less accessible to absolute novices.
  • Limited Coverage of Latest ES Features
    The book may not cover some of the latest features and best practices introduced in newer versions of JavaScript (e.g., ES2019 and beyond), meaning readers might need to supplement their learning with additional resources.
  • Web Development Sections Could Be More Detailed
    While the book does touch on web development, the sections on this topic are not as in-depth as some readers might hope. Those looking to get a more thorough grounding in web development may need to consult other sources.
