    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 Eloquent JavaScript and BreedTools.app.

What makes your product unique?

BreedTools.app's answer:

BreedTools is the only free breeding management PWA that covers the full breeding lifecycle — from heat cycle and progesterone tracking to live whelping logs, Volhard temperament testing with automatic buyer-puppy matching, digital contracts, and a complete stud owner module with frozen semen inventory. It works offline, requires no app download, and runs on any device instantly.

Why should a person choose your product over its competitors?

BreedTools.app's answer:

BreedTools is free where competitors charge, more feature-complete than anything at its price point, and works offline without an app install. It includes features competitors don't offer at any price — Volhard temperament testing with buyer matching, frozen semen inventory tracking, semen analysis records, verified stud service reviews, and a full 7-stage buyer CRM. Pro is $9/month versus $10-12/month for less capable alternatives.

How would you describe the primary audience of your product?

BreedTools.app's answer:

Serious hobby and professional dog breeders — AKC registered breeders, kennel owners, and stud dog owners who manage multiple dogs, litters, and buyers and need more than a spreadsheet. Also serves breeders entering their first litter who want a professional setup from day one.

What's the story behind your product?

BreedTools.app's answer:

BreedTools was built by a solo founder who saw that existing breeder software was either too expensive, too basic, or too clunky for how real breeders work. Starting with a free tools site at breedtools.com, the platform expanded into a full PWA so breeders could manage their entire program — from first heat cycle to puppy go-home day — in one place, free, on any device.

Which are the primary technologies used for building your product?

BreedTools.app's answer:

Next.js, React, Supabase (PostgreSQL), Stripe, Resend, Vercel, Progressive Web App (service worker with offline caching and push notifications)

Who are some of the biggest customers of your product?

BreedTools.app's answer:

  • Independent AKC registered dog breeders
  • Multi-breed kennel owners
  • Stud dog owners managing service requests

    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
