  • 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.

  • 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.
  • Athlete & Team Management
    Athlete profiles, teams and sub-teams, sport-specific positions, Excel import and encrypted document storage (KVKK/GDPR).
  • Fee & Payment Tracking
    Automatic monthly fee generation, collections and overdue tracking, receipts, plus bookkeeping: income/expense, accounts and reports.
  • Attendance Tracking
    Session attendance with absence reasons, attendance rates per athlete and team, visible to parents.
  • Training Plans & Evaluation
    Drill library, tactical drawing board, training plans, match statistics and evaluation templates that adapt to the selected sport (15 sports).
  • Parent Portal & Communication
    Parents see attendance, fees and announcements in the app; bulk WhatsApp messaging and rule-based automation for the club.

Questions & Answers

As answered by people managing Eloquent JavaScript and Ten Number.

What makes your product unique?

Ten Number's answer:

  • Every module in every plan. Plans differ only in athlete and coach capacity; attendance, fees, bookkeeping, parent portal, store and automation are never locked behind an upsell.
  • Adapts to the sport. Positions, drill library, tactical board, match statistics and evaluation templates change with the selected sport (15 sports, from football and basketball to swimming, archery and water polo).
  • Runs the business, not only the roster. Automatic monthly fee generation, overdue tracking, receipts, income/expense and account reports sit next to attendance and training.
  • Parents are in the loop. A parent portal shows attendance, fees and announcements; bulk WhatsApp messaging and rule-based automation handle reminders.
  • Privacy by design. Athlete documents and health fields are encrypted at rest (KVKK/GDPR).
  • Web and mobile (iOS/Android) in one subscription, interface in 14 languages, built in Türkiye.

Why should a person choose your product over its competitors?

Ten Number's answer:

Most club apps focus on scheduling and team chat. Ten Number covers that, but it also runs the financial and administrative side of a sports school: fee generation and collections, bookkeeping, club store with inventory, staff and leave management, asset tracking. A club owner does not need a second tool for money.

Compared with desktop-era club software, it is web + mobile, multi-branch, works from the field on a phone, and gives parents their own app view instead of PDF reports.

Pricing is transparent and local: monthly plans in Turkish lira by athlete capacity, no per-module add-ons, no credit card to start.

How would you describe the primary audience of your product?

Ten Number's answer:

Owners and managers of sports schools, academies and clubs with roughly 50 to 400 athletes, mainly youth sports. Three groups use it every day:

  • Owners / administrators track fees, collections, attendance rates and reports on the web.
  • Coaches take attendance, plan training and record match statistics from the mobile app on the field.
  • Parents follow their child's attendance, fees and announcements through the parent portal.

The primary market is Türkiye; the interface is available in 14 languages.

What's the story behind your product?

Ten Number's answer:

Ten Number started inside a sports academy, not a software company. The founder runs a youth academy and kept juggling spreadsheets for attendance, a separate notebook for fees and WhatsApp groups for parents, none of which talked to each other.

The first version, called "10n", was built in 2026 to replace that stack for one academy. It grew into a multi-tenant platform for sports schools and clubs, with the web app, the mobile app and the parent portal sharing one data model. The name "Ten Number" is the English reading of 10n.

Which are the primary technologies used for building your product?

Ten Number's answer:

  • Backend: .NET 9 (ASP.NET Core Web API), Clean Architecture with CQRS (MediatR), PostgreSQL 16, Redis
  • Web app: React 18, TypeScript, Vite, TailwindCSS, TanStack Query
  • Mobile app: React Native (Expo), shared core logic with the web app
  • Infrastructure: Docker on Hetzner, Cloudflare in front; athlete documents and health fields encrypted at rest (AES-256-GCM)
  • Messaging: WhatsApp integration for bulk messages and rule-based automation

    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
