What each product offers, as listed by its team.

EJS
Eloquent JavaScript 5 features
ATS First 10 features
  • Comprehensive Learning Resource
    Eloquent JavaScript covers a wide range of topics, from basic syntax to advanced concepts like asynchronous programming and web development. This depth makes it a valuable resource for both beginners and advanced programmers.
  • Interactive Code Examples
    The book contains numerous interactive code examples that allow readers to see the effects of their code in real-time. This hands-on approach reinforces learning and helps solidify concepts.
  • Free Online Access
    Eloquent JavaScript is available for free online, making it accessible to anyone with an internet connection. This allows learners from around the world to benefit from its content without financial barriers.
  • Engaging Writing Style
    The author, Marijn Haverbeke, writes in an engaging and clear style, making complex topics more understandable and keeping readers interested.
  • Good Balance of Theory and Practice
    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.
  • JD-specific ATS score
    Scores a resume against one specific job description rather than grading it in isolation, so the result reflects the job actually being applied for.
  • Missing-keyword gap report
    Lists the exact terms the job description expects and the resume is missing, turning the score into a concrete set of edits.
  • ATS-safe resume builder
    Builds resumes in templates that parse cleanly through applicant tracking systems, with live preview and PDF and DOCX export.
  • AI Resume Parsing
    Imports an existing resume and extracts the sections automatically, so users start from their real history instead of a blank page.
  • Cover Letter Builder
    Writes and formats cover letters in templates matching the resume, with a library of complete examples by job title and industry.
  • AI voice interview coach
    Runs spoken mock interviews tailored to a role or pasted job description, returning a transcript, delivery metrics and scored feedback on each answer.
  • Interview question banks
    Question sets by role and by company, with round-by-round process notes and answer strategies.
  • Free job-seeker tools
    JD keyword extractor, STAR answer builder, LinkedIn headline generator, salary and notice-period calculators, and free Word resume and biodata formats, all without signup.
  • Recruiter screening tools
    Bulk resume screening, boolean search builder, job description generator and interview scorecards for small hiring teams.
  • One-time passes, no subscription
    Pro is sold as a 7-day, 1-month or 3-month pass that expires on its own. Nothing auto-renews, and a free tier stays available without a card.

Questions & Answers

As answered by people managing Eloquent JavaScript and ATS First.

What makes your product unique?

ATS First's answer:

Most resume tools score a resume in isolation and hand you a number. ATS First scores it against a specific job description and then shows the exact keywords the ATS is looking for and your resume is missing — so the fix is a concrete edit, not a vague grade.

It's also the whole loop in one place: check the resume, rebuild it in an ATS-safe template, write the matching cover letter, then run a voice mock interview for that same role and get scored feedback on your answers. Most competitors do one of those four.

And it isn't a subscription. Pro is a one-time, time-limited pass (7-day, 1-month, 3-month) with no auto-renewal — you buy it for the job search, it ends by itself.

Why should a person choose your product over its competitors?

ATS First's answer:

  • Scoring is job-description-specific, with a missing-keyword gap report, not a generic resume grade.
  • No subscription and no auto-renewal. A 7-day pass is $5 and simply expires — you're never billed again by surprise.
  • The free tier is real, not a paywalled preview: 3 analyses a month, a saved resume, a cover letter, and PDF export without a card.
  • One product covers resume check, resume builder, cover letters and AI voice mock interviews, so you aren't paying three vendors.
  • Exports are genuinely ATS-safe (PDF and DOCX), not design-heavy templates that parse badly.
  • India-first pricing in INR alongside USD, plus content built for the Indian market (biodata formats, fresher resume formats, notice-period and CTC calculators) that global tools ignore.
  • Dozens of free tools and guides with no signup — JD keyword extractor, STAR answer builder, interview question banks by role and by company.

How would you describe the primary audience of your product?

ATS First's answer:

Job seekers applying online who get filtered out before a human sees the resume — mid-career professionals switching roles, freshers and recent graduates writing a first resume, and career changers who need to re-target their experience for a new function. Strongest in India, where the free Word formats, biodata and CTC/notice-period tools are built for local hiring norms, with a growing global user base paying in USD.

A second, smaller audience is recruiters and small hiring teams using the bulk resume screening, boolean search builder, JD generator and interview scorecard tools.

What's the story behind your product?

ATS First's answer:

ATS First started from a simple, common frustration: qualified people sending out dozens of applications and hearing nothing, because an Applicant Tracking System filtered the resume out before any human read it. The advice online was generic — "use keywords" — with no way to know which keywords, for which job.

So the first thing built was the piece that was missing: score a resume against one specific job description and name the exact terms it's missing. Everything since has followed the same rule — every feature has to change what the user does next, not just report a number. That's how the ATS-safe builder, the cover letter tools and the AI interview coach were added.

The pricing follows from the same idea. A job search is a season, not a forever subscription, so Pro is sold as a one-time pass that expires on its own.

Which are the primary technologies used for building your product?

ATS First's answer:

  • Next.js 15 (App Router) with React 19 and TypeScript, deployed on Vercel
  • Tailwind CSS 4
  • Firebase — Authentication, Firestore, Cloud Functions, App Check
  • Google Gemini on Vertex AI for resume analysis, generation and interview scoring
  • Google Cloud Text-to-Speech for the voice interview coach
  • Razorpay (INR) and Dodo Payments (USD) for checkout

    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
