Sherlo 6 features
JST
JavaScript Tutorial 5 features
  • iOS & Android simulators
    Renders your app on real iOS and Android simulators in the cloud - no device farm to manage.
  • Pixel-by-pixel diffs
    Screenshots every screen and compares each against the previous version, flagging changed pixels.
  • Team review app
    Developers, designers, PMs and QA review changes together and approve or reject before release.
  • Storybook integration
    Turns your existing Storybook stories into an automated visual test suite.
  • CI integration
    Runs in CI on every build via the CLI; both platforms in one run.
  • Device/theme/language matrix
    Test across many devices, screen sizes, themes and languages from one config.
  • Accessible Learning Format
    Delivered as a mobile/web app, allowing learners to study JavaScript concepts on-the-go from their smartphones without needing a desktop setup.
  • Free or Low-Cost Access
    Apps built on platforms like AppCreator24 are often free or inexpensive, making it easy for beginners to start learning JavaScript without financial commitment.
  • Beginner-Friendly Structure
    Likely organized into simple, bite-sized lessons or modules that help newcomers grasp basic JavaScript syntax and concepts step-by-step.
  • Convenient for Quick Reference
    Useful as a quick-reference tool for reviewing JavaScript basics such as variables, functions, and loops without needing to search through lengthy documentation.
  • No Installation of Development Tools Required
    Since it's app-based, users can review tutorial content without setting up a full coding environment, which is helpful for on-the-go review.

Possible disadvantages

  • Limited Interactivity
    Unlike dedicated coding platforms (e.g., Codecademy or freeCodeCamp), apps built with generic app builders like AppCreator24 often lack live code editors or interactive exercises for hands-on practice.
  • Potentially Outdated or Shallow Content
    Tutorials hosted on third-party app-building platforms may not be regularly updated to reflect modern JavaScript (ES6+) features or best practices.
  • No Community or Support System
    Lacks the peer support, forums, or instructor access found in established learning platforms, making it harder to get help when stuck.
  • Unverified Credibility of Content Creator
    Since this is a user-generated app rather than content from a recognized educational institution or established tutorial site, the accuracy and depth of the material may be inconsistent or unverified.
  • Limited Scalability for Advanced Topics
    Such apps are typically designed for basic tutorials and may not adequately cover advanced JavaScript topics like asynchronous programming, closures, or frameworks (React, Node.js, etc.).

  • Free and accessible without requiring account creation or payment
  • Simple, beginner-friendly presentation of core JavaScript concepts
  • Useful as a quick reference for basic syntax and examples
  • Low barrier to entry for people just starting to explore programming

Recommended for

  • Absolute beginners wanting a quick, no-cost introduction to JavaScript basics
  • Learners looking for simple reference material rather than in-depth courses
  • Users who want a supplementary resource alongside more comprehensive tutorials
  • Casual learners exploring whether they enjoy coding before committing to structured courses

Questions & Answers

As answered by people managing Sherlo and JavaScript Tutorial.

What makes your product unique?

Sherlo's answer

Sherlo is the visual regression testing tool built specifically for React Native. It renders your app on real iOS and Android simulators in the cloud - native rendering, not React Native Web - and diffs every screen pixel by pixel. Web-first tools like Percy, Chromatic, and Applitools can't test how a React Native app actually looks on a device; Sherlo does.

Why should a person choose your product over its competitors?

Sherlo's answer

Because it's the React Native specialist. Percy, Applitools, and Chromatic are multi-platform generalists that test web-framework Storybook in a browser, not native iOS/Android rendering. Sherlo runs your app on real iOS and Android simulators, covers both platforms in one run, plugs into CI, and includes the cloud simulators from a free plan - no device farm, no credit card.

How would you describe the primary audience of your product?

Sherlo's answer

React Native teams that ship UI frequently - developers, designers, PMs, and QA who want to catch visual regressions before release. It fits teams already using Storybook and anyone shipping to many devices, themes, and languages who can't check them all by hand.

What's the story behind your product?

Sherlo's answer

Sherlo was built by React Native developers who kept shipping UI bugs that slipped past functional tests and were painful to catch by hand across devices. Existing tools were web-first and didn't test native mobile rendering - so they built the visual testing tool they wanted for React Native.

Which are the primary technologies used for building your product?

Sherlo's answer

React Native, TypeScript, an open-source SDK/CLI (github.com/sherlo-io/sherlo), cloud-hosted iOS and Android simulators, and a web app for reviewing diffs. Integrates with Storybook and any CI pipeline.
