Blockly features and specs

  • User-Friendly
    Blockly offers a highly intuitive and visual interface. Users, especially beginners and non-programmers, can easily drag and drop blocks to create programs without needing to write code manually.
  • Educational Value
    Blockly is excellent for educational purposes. It simplifies the learning curve for programming by abstracting the complexities of syntax, allowing learners to focus on understanding logic and computational thinking.
  • Cross-Language Support
    Blockly can generate code for multiple programming languages (JavaScript, Python, PHP, Lua, Dart). This makes it versatile and useful for teaching and transitioning to various languages.
  • Customizability
    Blockly is highly customizable. Developers can create custom blocks and define their own rules, making it adaptable to various projects and domain-specific needs.
  • Open Source
    As an open-source project, Blockly provides the flexibility to modify and extend the toolkit to fit specific requirements. This open nature encourages community contributions and improvements.

Possible disadvantages of Blockly

  • Limited Complexity
    Blockly is designed for simplicity and may not handle very complex programming tasks efficiently. Advanced users might find it insufficient for sophisticated or large-scale projects.
  • Performance Overhead
    The visual programming model can introduce performance overhead. Converting blocks to executable code and running it can be less efficient compared to hand-written code, especially for performance-critical applications.
  • Learning Transition
    While Blockly is great for beginners, transitioning from block-based programming to traditional text-based coding can be challenging. Users may need additional guidance to adapt to the intricacies of syntax and coding best practices.
  • Limited Debugging Tools
    Blockly does not offer advanced debugging tools. Debugging issues can be more challenging compared to traditional IDEs that provide sophisticated debugging capabilities.
  • Scalability Issues
    For large projects, the block-based approach can become unwieldy and harder to manage compared to traditional text-based code which can be more neatly structured and maintained.

OpenSilver features and specs

  • Cross-Platform Compatibility
    OpenSilver enables developers to create applications that run on multiple platforms, including web browsers, by leveraging WebAssembly, which enhances the reach and accessibility of applications originally written in Silverlight.
  • Silverlight Code Reusability
    Since OpenSilver supports C# and XAML, much of the existing Silverlight code can be reused, minimizing migration efforts and reducing time and costs associated with redevelopment.
  • WebAssembly Based Performance
    By utilizing WebAssembly, OpenSilver applications can achieve near-native performance, leading to efficient and responsive user experiences in web applications.
  • Open Source Flexibility
    As an open-source project, OpenSilver offers developers the ability to contribute to and modify the platform, fostering a community-driven environment and encouraging innovation.
  • Integration with Modern Web Technologies
    OpenSilver allows integration with modern web technologies and frameworks, enabling developers to enhance applications with contemporary features and functionalities.

Possible disadvantages of OpenSilver

  • Incomplete Feature Support
    Not all of Silverlight's features are fully supported in OpenSilver, which might necessitate additional workarounds or re-implementations for complex applications.
  • Learning Curve for Migration
    Developers familiar with Silverlight may need to learn new patterns and practices related to web development and WebAssembly when transitioning to OpenSilver.
  • Browser Compatibility
    While WebAssembly aims to be universally compatible, some differences in performance and behavior might occur across various browsers, potentially requiring additional testing and optimization.
  • Community and Support Maturity
    As a relatively new and open-source project, OpenSilver might have a less mature support ecosystem compared to more established platforms, impacting the availability of resources and community support.
  • Dependency on WebAssembly
    OpenSilver's reliance on WebAssembly means that any limitations or ongoing development challenges associated with WebAssembly could directly impact the capabilities and performance of OpenSilver applications.

Blockly Reviews

Top 20 Javascript Libraries
Blockly, a creation of Google, is a web-based visual programming editor. When added to the code, the library adds an editor to the app that represents code snippets like loops, expressions, variables, and more as blocks. The best part is that you can create custom code, and the output is syntactically correct in your choice of the programming language. Blockly has no...

  • Ask HN: Platform for 11 year old to create video games?
    Scratch is fantastic. There are also a number of similar (block-based) tools that let you create your own custom blocks and see the code behind them - e.g. Blockly (https://developers.google.com/blockly). - Source: Hacker News / almost 2 years ago
  • Ask HN: Modern Day Equivalent to HyperCard?
    If your kid is already doing Scratch, Blockly is a really easy next step. https://developers.google.com/blockly Critically, Blockly can emit JavaScript and Python, plus it supports plugins for extended functionality. So the kid can stay inside the blockly universe for as long as they like, but easily peer under the hood and get into Python or JavaScript as soon as they like. - Source: Hacker News / about 2 years ago
  • A shortage of teachers for computer science classes in California
    The issue with Alice is that graphical, block based coding is not at all an ergonomic way to code. Sure, C++ probably isn't the best for an intro CS courses, either, but even just Python with some wrappers over SDL to draw sprites is not only a better teaching tool it's also forms a more useful springboard to build other projects. Graphical, block based coding seems to be a common attempt to make coding more... - Source: Hacker News / over 2 years ago

    - XAML autocompletion, AI error fixing, split editor views The visual designer is the differentiator: 100+ drag-and-drop controls for building UIs. But the NuGet and sharing features work even if you ignore the designer entirely and just write C# code. XAML.io is currently in tech preview.

    I would also say that IF blazor worked on a browser plugin like silverlight did, today that's not the case it is built on the webassembly standard which and it is being adopted in the browsers which means once it gets on the web, it is unlikely to ever go out again. Even if Microsoft themselves leave Blazor today, it can still work, the burden of creating a fork and keeping blazor alive will certainly be big but... - Source: dev.to / over 2 years ago
