    The book strikes a good balance between theoretical explanations and practical exercises, allowing readers to apply what they have learned immediately.

Possible disadvantages

  • Steep Learning Curve
    Some readers may find the book's progression to be rapid, especially if they are complete beginners. The book quickly moves from basic to more complex topics, which can be overwhelming.
  • Lacks Visual Aids
    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.

Questions & Answers

As answered by people managing CrabPod and Eloquent JavaScript.

Which are the primary technologies used for building your product?

CrabPod's answer

Swift and SwiftUI for iOS, with Core Data for local storage. Native iPhone and iPad app.

What's the story behind your product?

CrabPod's answer

After building InvertMate for tarantula and scorpion keepers, the developer realized hermit crabs and isopods need a completely different approach. They're colony animals, not individual pets. So he built CrabPod with colony-specific features like population tracking, environment health monitoring, and group care reminders.

What makes your product unique?

CrabPod's answer

CrabPod is the only app designed specifically for hermit crab and isopod keepers. It includes colony population tracking, environment monitoring (temperature and humidity), molt logging, shell change tracking, and care reminders. No other app addresses the unique needs of colony-based invertebrate keeping.

Why should a person choose your product over its competitors?

CrabPod's answer

There are no real competitors. Generic pet apps don't support colony tracking, humidity monitoring, or shell change logs. CrabPod was built from the ground up for how hermit crab and isopod keepers actually care for their animals. It's free with no ads.

How would you describe the primary audience of your product?

CrabPod's answer

Hermit crab owners and isopod hobbyists, from first-time keepers setting up their crabitat to breeders managing multiple isopod colonies. Many are active on Reddit (r/hermitcrabs, r/isopods) and Facebook groups dedicated to these species.

    Seconded. I won't recommend it and no one I know has recommended it for a decade. It's hard for someone who doesn't know JS to know which parts has changed and is no longer the way to do things. https://github.com/getify/You-Dont-Know-JS... - Source: Hacker News / about 2 years ago
