JavaScript Operator Lookup 5 features
Ten Number 5 features
  • Ease of Use
    The JavaScript Operator Lookup tool provides a simple and easy-to-use interface for developers to quickly find information about JavaScript operators, improving their coding efficiency.
  • Comprehensive Information
    The tool offers a comprehensive list of JavaScript operators along with detailed explanations, examples, and related information, which can be very helpful for both beginners and experienced developers.
  • Time-Saving
    By consolidating information about JavaScript operators in one place, the tool saves developers time they might otherwise spend searching through documentation or other online resources.
  • Educational Resource
    The tool acts as an educational resource by not only listing operators but also explaining their functionality and use cases, aiding in the learning process.
  • Responsive Design
    With a responsive design, the tool is accessible across different devices, ensuring that developers can use it whether they are on a desktop, tablet, or mobile device.

Possible disadvantages

  • Dependency on Internet
    Since the tool is web-based, it requires an internet connection, which may not be available in all situations, potentially limiting accessibility.
  • Scope Limited to Operators
    The tool focuses solely on JavaScript operators, which might not cover all the needs of a developer looking for comprehensive JavaScript resources or help with other language features.
  • Potential for Outdated Information
    There is a potential risk of the information becoming outdated if the tool is not regularly maintained and updated to reflect the latest changes in the JavaScript language.
  • Lack of Interactive Examples
    While the tool provides examples, the absence of interactive coding environments means users cannot test operators directly within the tool.
  • 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).

    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 JavaScript Operator Lookup 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

    If you replace your || with ?? You should get the behaviour you are after. This is a good reference for what the operators do in js: https://joshwcomeau.com/operator-lookup. Source: about 5 years ago
