Haskell features and specs

  • Pure Functional Programming
    Haskell emphasizes pure functional programming, meaning functions have no side effects. This leads to code that is easier to understand, test, and maintain.
  • Strong Type System
    Haskell's type system is strong and expressive, allowing developers to catch many errors at compile time. This results in more reliable code.
  • Lazy Evaluation
    Haskell uses lazy evaluation by default, which can lead to performance improvements by avoiding unnecessary computations and enabling the creation of infinite data structures.
  • Immutability
    In Haskell, data is immutable by default. This leads to simpler reasoning about code behavior and reduces bugs related to mutable state.
  • High-Level Abstractions
    Haskell provides powerful abstractions like monads, functors, and applicative functors, which can lead to more concise and expressive code.
  • Concurrency
    Haskell has excellent support for concurrency and parallelism through its lightweight threading model and software transactional memory, making it suitable for concurrent applications.
  • Community and Libraries
    Haskell has a dedicated community and a rich set of libraries and tools, which can help accelerate development and provide solutions to common problems.

Possible disadvantages of Haskell

  • Steep Learning Curve
    Haskell has a steep learning curve, particularly for developers who are new to functional programming or coming from imperative and object-oriented backgrounds.
  • Performance Concerns
    While Haskell can be efficient, its performance can sometimes lag behind other languages like C++ or Rust for certain use cases, especially those requiring low-level optimization.
  • Limited Industry Adoption
    Haskell is not as widely adopted in industry compared to languages like Java, Python, or JavaScript, which can limit job opportunities and community size.
  • Compilation Times
    Haskell's compilation times can be long, especially for large projects, which can slow down the development process.
  • Tooling and IDE Support
    While improving, the tooling and IDE support for Haskell is not as mature as for some other popular languages, potentially affecting developer productivity.
  • Complexity of Advanced Features
    Some of Haskell's advanced features, such as monads and type-level programming, can be complex and difficult to master, which can be a barrier for new developers.
  • Library Gaps
    Although Haskell has many libraries, there might be gaps or less mature libraries for some specific use cases compared to more mainstream languages.

REBOL features and specs

  • Simplicity
    REBOL is designed to be extremely simple and easy to learn, with a small footprint and a straightforward syntax that makes it accessible to beginners and quick for experienced developers to use.
  • Compactness
    REBOL code is usually very concise, often requiring fewer lines of code to accomplish tasks compared to other languages, which can lead to faster development cycles.
  • Cross-platform
    REBOL can run on multiple platforms with little to no modification of the code, enhancing its utility in diverse environments.
  • Network and Internet Orientation
    REBOL was designed with networking in mind, providing built-in support for various protocols and making it well-suited for internet applications.
  • Domain-Specific Language (DSL) Focus
    The language enables the creation of highly customizable DSLs, allowing developers to tailor the coding environment closely to the problem domain.

Possible disadvantages of REBOL

  • Limited Libraries and Community Support
    REBOL's ecosystem is not as robust as those of more popular languages, which can limit the availability of libraries and community support for newcomers and developers.
  • Performance
    REBOL is not primarily designed for high-performance computing. It can be slower in execution compared to other languages optimized for performance.
  • Proprietary Nature
    Certain versions and tools related to REBOL have historically been proprietary, which can be a concern for developers and organizations wanting open-source solutions.
  • Lack of Modern Features
    REBOL lacks some of the modern programming features found in newer languages, which can be a drawback for developers accustomed to more contemporary programming paradigms.
  • Limited Documentation
    The available documentation and resources for REBOL are not as extensive as for more popular programming languages, potentially making it more challenging to learn and adopt.

Analysis of Haskell

Overall verdict

  • Haskell is good for certain types of projects and developers, especially those interested in functional programming and academic exploration. It may not be the best choice for every use case, particularly where performance-critical applications or system-level programming is required, due to its steep learning curve and relatively smaller community compared to more mainstream languages.

Why this product is good

  • Haskell is a purely functional programming language known for its high level of abstraction, robust type system, and lazy evaluation. These features make Haskell an excellent choice for academic research, complex algorithm design, and scenarios where concise and maintainable code is paramount. It encourages a different way of thinking about programming problems, which can lead to more elegant and robust solutions.

Recommended for

  • Developers interested in functional programming paradigms
  • Projects focused on academic research or algorithm development
  • Software requiring high-level abstractions and strong type safety
  • Enthusiasts wishing to learn a different approach to thinking about software design

Haskell mentions (21)

  • Is there a programming language that will blow my mind?
    Haskell - a general-purpose functional language with many unique properties (purely functional, lazy, expressive types, STM, etc). You mentioned you dabbled in Haskell, why not try it again? (I've written about 7 things I learned from Haskell, and my book is linked at them bottom if you're interested :) ). Source: about 2 years ago
  • Where to go from here?
    Where you go is entirely up to you. According to haskell.org, Haskell jobs are a-plenty. sigh. Source: about 2 years ago
  • Haskell.org now has "Get Started" page!
    Should they be part of haskell.org or something else? Source: over 2 years ago
  • Haskell.org now has "Get Started" page!
    Haskell.org now has a big purple Get Started button that takes you to a nice short guide (haskell.org/get-started) that quickly provides all the basic info to get going with Haskell. It is aimed for beginners, to reduce choice fatigue and to give them a clear, official path to get going. Source: over 2 years ago
  • dev environment for windows
    I just jumped into the wiki "Write Yourself a Scheme in 48 hours" which looks pretty good. (although some of the text explanation is hard to understand without context).. I used cabal to set up the starter project. Sublime editor seems to work OK and I just use the git Bash shell on windows to compile the program directly on the command line. So maybe this is all good enough for now (?). It seems installing... Source: over 2 years ago
