D (Programming Language) features and specs

  • Performance
    D is designed to be a high-performance systems programming language, offering performance comparable to C and C++ through native machine code compilation.
  • Expressiveness
    D features a rich standard library and modern language constructs, such as garbage collection, first-class arrays, and advanced templating, making it easier to write expressive and maintainable code.
  • Memory Safety
    D offers optional garbage collection along with manual memory management. This hybrid approach can help in developing safer applications by reducing memory-related errors.
  • Interoperability
    D can easily interoperate with C API, enabling seamless integration with existing C libraries and systems. It also supports better C++ interoperability compared to other languages.
  • Built-in Unit Testing
    D has built-in support for unit tests, allowing developers to write and run tests as part of the language itself, facilitating test-driven development.
  • Concurrency
    D offers built-in concurrency support with message passing, similar to the actor model found in languages like Erlang, making it easier to write concurrent and parallel programs.

Possible disadvantages of D (Programming Language)

  • Adoption
    D is not as widely adopted as other languages like C, C++, or Java. This limited adoption means fewer libraries, frameworks, and community support.
  • Toolchain Maturity
    While D's compilers and tools have improved over the years, they may still lack the maturity and feature set of more established languages, which can affect developer productivity.
  • Learning Curve
    D's richness and combination of paradigms (such as imperative, object-oriented, and functional programming) can present a steep learning curve for new developers.
  • Garbage Collection
    Although D offers optional garbage collection, its reliance on it for memory safety might be seen as a drawback for real-time system development where deterministic memory management is crucial.
  • Ecosystem
    The ecosystem for D is less vibrant compared to more popular languages, leading to potentially fewer third-party libraries, tools, and resources.
  • Standard Library Documentation
    The standard library documentation can be inconsistent or less comprehensive compared to other languages, making it difficult for developers to fully utilize all features of the language.

Transcrypt features and specs

  • Python to JavaScript Transpilation
    Transcrypt allows you to write your code in Python, which is then transpiled into JavaScript. This enables Python developers to leverage their existing knowledge and skills to develop web applications.
  • Efficiency and Performance
    Transcrypt produces highly readable and compact JavaScript code, which can be optimized for better performance. The generated code includes optional source maps for debugging.
  • Access to JavaScript Libraries
    Transcrypt allows you to use JavaScript libraries seamlessly alongside Python code, enabling integration with existing JavaScript ecosystems.
  • Static Typing
    Transcrypt supports optional static typing, which can help catch errors earlier in the development cycle and make your code more robust.
  • Advanced Features
    Transcrypt supports advanced Python features such as multiple inheritance, tuple assignment, and list comprehension, providing a rich development experience.

Possible disadvantages of Transcrypt

  • Limited Python Support
    Only a subset of Python's standard library is supported, which might limit functionality that can be directly transpiled without modifications.
  • Compatibility Issues
    Certain Python constructs and idioms may not translate well into JavaScript, requiring developers to adapt their code specifically for web environments.
  • Learning Curve
    Although it enables Python development for the web, developers need to learn about the limitations and specifics of the transpilation process, which can be a barrier.
  • Community and Support
    Transcrypt has a smaller community compared to mainstream JavaScript frameworks, which can make finding support and resources challenging.
  • Development Overhead
    Transcrypt introduces an additional step in the build process, which might increase the complexity of the development and deployment workflow.

Analysis of D (Programming Language)

Overall verdict

  • Overall, D is a solid programming language choice that balances performance with productivity. It may not be as widely adopted as some other languages, but it has a dedicated community and continues to evolve, making it a viable option for various programming tasks.

Why this product is good

  • The D programming language is considered good by many developers for various reasons. It combines the performance and low-level control of C/C++ with the expressive power and ease of use found in modern languages. D offers features like garbage collection, first-class functions, and compile-time function execution, providing both speed and flexibility. Its interoperability with C, the convenience of a powerful standard library (Phobos), and the availability of packages via the DUB package manager make it a practical choice for systems programming, application development, and rapid prototyping.

  • Ask HN: What is your (AI) dev tech stack / workflow? (June 2026)
    I've spent 2 weeks (2-4h per day) to make D language[1] version of Sciter SDK [2] Choice of AI "tooling" was by accident - typed something like "how to define copy constructor in D for custom structure" in Microsoft's Copilot in Edge browser that gives context for AI.

    > Mostly, I am not really trying to compete with C/C++/Rust on speed, but I'm not going to add a GC either. So I'm somewhere in there.

  • PyScript
    This is a laudable effort, but I'm not a fan of shipping the entire interpreter. I looked around a few weeks ago and found https://transcrypt.org, which compiles your Python script to JS, so size is minimal. It's great for shipping small, internal tools/apps, I love how maintainable they are by all the Python devs, plus they're very fast to load and execute. - Source: Hacker News / about 4 years ago
  • PySketch: Python Playground for HTML5
    How is the Python being run by the browser? Several impressive projects bring Python to the browser, such as Brython, Transcrypt, Skulpt, Pyodide. PySketch uses Brython that compiles Python to JavaScript in the browser. You can take a look at this article about technologies and comparisons if you want to learn more. - Source: dev.to / over 4 years ago
  • How to actually use python code in browser or application?
    I have a Python program that takes user input from the console and shows some results on the console, and I want the user to be able to type stuff into it instead of pre-recorded runs. How do I do that? I'm not really sure. You could have a copy of Python running on the server and have the front-end communicating with it, but you'd have to be sure it's secured -- there are a lot of dangerous Python commands...

  • Use of python for software development
    For web apps: in my experience, there are tools that convert Python into JavaScript or try to make Python run inside a web browser like Brython and Transcrypt. These have been VERY awkward or painfully slow, so I would strongly discourage their use in practical web development. Source: about 5 years ago
