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 indexaction.

What makes your product unique?

indexaction's answer:

It checks whether a URL is in Google's index on any domain, including sites you don't own, which Search Console can't do. You paste up to 1,000 URLs and get one clear verdict per URL, with no CAPTCHA and no subscription.

Why should a person choose your product over its competitors?

indexaction's answer:

Most index checkers either sell a monthly plan or bundle checking with an "indexer" that promises to force pages into Google. indexaction only reports the truth: indexed or not. You pay per URL checked, credits never expire, and the same credits also track keyword rankings. There are 10 free checks with no signup, so you can try it before creating an account.

How would you describe the primary audience of your product?

indexaction's answer:

SEOs, link builders and agencies who buy or build backlinks and need to know which ones Google actually indexed, plus site owners who track their keyword rankings without paying for a full SEO suite.

What's the story behind your product?

indexaction's answer:

Checking whether backlinks were indexed meant typing site: queries into Google one at a time, and hitting a CAPTCHA every few minutes. Search Console couldn't help, because the links sit on other people's sites. indexaction automates that check in bulk and returns a plain verdict per URL.

Which are the primary technologies used for building your product?

indexaction's answer:

Django, Django REST Framework, Celery, PostgreSQL and Redis on the backend; React 19, Vite and Tailwind CSS for the app; Astro for the website; Cloudflare in front.

    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
