EJS
Eloquent JavaScript 5 features
EcoDiligence 5 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.
  • Specialized Environmental Focus
    EcoDiligence appears to specialize in environmental due diligence and sustainability assessments, which can provide clients with expert, niche knowledge that generalist consulting firms may lack.
  • Supports ESG Compliance
    The service likely helps businesses and investors meet growing regulatory and stakeholder demands around Environmental, Social, and Governance (ESG) reporting and compliance.
  • Risk Mitigation for Transactions
    By conducting environmental due diligence, the company can help clients identify potential environmental liabilities before mergers, acquisitions, or property transactions, reducing financial and legal risk.
  • Growing Market Relevance
    As sustainability becomes a bigger priority for investors and regulators, a company focused on eco-diligence is positioned in a high-demand, forward-looking market segment.
  • Potential for Customized Reporting
    Environmental due diligence firms often provide tailored reports and assessments specific to a client's industry, location, or transaction type, offering more relevant insights than generic tools.

Questions & Answers

As answered by people managing Eloquent JavaScript and EcoDiligence.

Who are some of the biggest customers of your product?

EcoDiligence's answer:

EcoDiligence recently launched publicly. We're onboarding early SME suppliers, consultants and accounting firms across Europe, Australia and Southeast Asia. Named customers will be listed here once public references are in place.

Why should a person choose your product over its competitors?

EcoDiligence's answer:

Three reasons: Purpose-built for the buyer-request problem. Most ESG platforms are carbon-accounting tools with reports bolted on. EcoDiligence starts from the disclosure a buyer will ask for and works backward. VSME- and ISSB-aligned in the same profile. One data model covers European buyers (VSME) and global capital markets (ISSB IFRS S1/S2) — with country-specific packs for Australia (AASB S2), the US (California SB 253/261), Japan (SSBJ), Singapore, India, Brazil and more. Structured outputs, not just PDFs. The EFRAG VSME XLSX workbook and XBRL instance are produced natively, so the disclosure is machine-readable by buyer systems and auditor tools — without a consultant re-entering data. The result: an SME can respond to a large customer's request in a single sitting instead of paying for weeks of consulting.

What makes your product unique?

EcoDiligence's answer:

EcoDiligence produces a single, structured ESG profile — an "ESG Passport" — that answers every buyer request at once, aligned with the EU VSME standard and ISSB IFRS S1/S2. The Passport is generated in three formats: a branded PDF report, the official EFRAG VSME XLSX workbook (v1.3.0), and an XBRL instance. Very few tools in this space produce the digital VSME and XBRL outputs directly; most stop at PDF. Built for SMEs pulled into disclosure by their large customers — not for enterprises with a dedicated sustainability team.

How would you describe the primary audience of your product?

EcoDiligence's answer:

Three audiences, in this order: SMEs and suppliers — companies with roughly 10–1,000 employees that have been asked by a large customer, bank or exporter to provide sustainability data. Typical caller: a CFO, operations lead or founder without an in-house ESG function. Consultants and advisors — sustainability consultants, accountants and bookkeepers who serve multiple SME clients and need a repeatable way to produce disclosures for them. Enterprise and procurement teams — larger buyers that want to receive structured, comparable disclosures from their SME suppliers instead of chasing bespoke spreadsheets.

What's the story behind your product?

EcoDiligence's answer:

EcoDiligence was built after seeing the same pattern repeat: a large buyer sends its SME supplier a sustainability questionnaire, the supplier has no in-house team, and the choice becomes either paying a consultant thousands or answering incompletely and risking the contract. The EU's VSME standard was designed precisely to fix this — a proportionate, standardised disclosure that a small company can produce once and reuse everywhere. EcoDiligence turns that standard into working software, and extends the same idea to ISSB and to jurisdiction-specific frameworks in Australia, the US, Japan, Singapore, Brazil and beyond.

Which are the primary technologies used for building your product?

EcoDiligence's answer:

Next.js 15 with TypeScript (strict) Supabase (Postgres, auth, storage) Clerk Organizations Anthropic Claude (assisted disclosure drafting) Paddle (billing, Merchant of Record) react-pdf/renderer for PDF output JSZip / TypeScript core for the EFRAG VSME Digital Template (XLSX) Native XBRL generation aligned with the EFRAG VSME taxonomy Resend, PostHog, Sentry, Upstash Redis Deployed on Vercel
