GHCJS features and specs

  • Haskell to JavaScript Compilation
    GHCJS allows developers to compile Haskell code to JavaScript, enabling the use of Haskellโ€™s advanced type system and functional programming features in web development.
  • Code Reusability
    Developers can reuse their Haskell codebase for both server-side and client-side applications, reducing code duplication and maintenance efforts.
  • Strong Type System
    Haskellโ€™s strong static type system helps in catching errors at compile time, which can result in more robust and reliable code for web applications.
  • Interoperability
    GHCJS provides interoperability with existing JavaScript libraries and modules, allowing developers to integrate Haskell into existing JavaScript ecosystems smoothly.

Possible disadvantages of GHCJS

  • Performance Overhead
    Generated JavaScript code may have performance overhead compared to native JavaScript, which can affect the execution speed of web applications.
  • Tooling and Ecosystem
    The GHCJS ecosystem and tooling may not be as mature or extensive as more established JavaScript frameworks, potentially leading to challenges in debugging and developer support.
  • Compilation Complexity
    The compilation process from Haskell to JavaScript can be complex, and build times might be longer compared to traditional JavaScript projects.
  • Limited Community and Support
    The GHCJS community is relatively smaller compared to mainstream JavaScript communities, which might limit the availability of resources, tutorials, and third-party libraries.

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.

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.

Recommended for

  • System programming enthusiasts looking for an alternative to C/C++
  • Developers interested in writing high-performance applications
  • Programmers who appreciate modern language features and strong community support
  • Projects requiring seamless C integration
  • Individuals looking for a language that supports easy code maintenance and scalability

  • Secretly introduced rust in my company, now they love it!
    There is a fork that compiles to js https://github.com/ghcjs/ghcjs compiler, and I believe the official glasgow compiler is working towards also supporting js/wasm (although I don't think they are supported as of yet). Source: over 3 years ago
  • Is GHCJS stuck on GHC 8.6.5?
    Default branch on ghcjs github is 8.6. 8.10 is a wip with commit from around a month ago. Source: over 5 years ago
  • Why Do We Need Transpilation into JavaScript?
    At present, here at Typeable we develop frontend in Haskell and use the web framework Reflex and the functional reactive programming (FRP). The source code in Haskell is transpiled into the JavaScript code using GHCJS. - Source: dev.to / over 5 years ago
  • Why supporting all programming languages is a bad idea
    In theory it is possible to write applications that run in the web browser in Java or C# or C++. There are compilers to compile Java to JavaScript or C++ to JavaScript/WebAssembly and a C# runtime that runs in the browser. In practice these technologies are very niche and only used for very few applications. The Cardano Wallet Daedalus is written in JavaScript even though most of the software for Cardano is...

    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.
