  • User Engagement
    The platform encourages community interaction through comments, user-submitted challenges, and solutions, fostering a collaborative learning environment.
  • Multiple Languages
    Codewars supports a variety of programming languages, allowing users to practice and improve skills in their language of choice.

    The use of a ranking system, badges, and honor points adds a gamified layer to the learning process, making it more engaging and motivating.
  • Detailed Solutions
    After solving a challenge, users can view multiple solutions from others, offering a range of approaches and insights into problem-solving.

Possible disadvantages of Codewars

  • Steep Learning Curve
    Beginners might find some challenges too difficult at first, which can be discouraging without proper guidance or learning resources.
  • Quality Variability
    The quality of user-submitted challenges can be inconsistent, meaning not all katas are equally useful or well-designed.
  • Limited In-Depth Learning
    While great for practice, Codewars does not provide comprehensive tutorials or in-depth explanations, which are often needed for mastering complex concepts.
  • Time Consumption
    The addictive nature of the platform can lead to spending excessive time on solving challenges, potentially detracting from other learning activities.

MLton features and specs

  • Performance
    MLton is known for producing highly optimized, efficient executables due to its whole-program compilation approach. This can result in faster performance compared to other Standard ML compilers.
  • Standard ML Compliance
    MLton has strong adherence to the Standard ML language specification, ensuring that programs written for MLton are highly portable and conform to the expected language standards.
  • Rich Optimization
    The compiler includes numerous optimization techniques, enabling better runtime performance and memory usage for compiled applications.
  • Large Language Support
    MLton supports the full breadth of the Standard ML language, including advanced features like functors and modules.

Possible disadvantages of MLton

  • Compilation Time
    Due to its whole-program optimization techniques, MLton can take longer to compile programs compared to other compilers that use separate compilation.
  • Executable Size
    Although MLton optimizes for performance, this can sometimes result in larger executable sizes than compilers that don't perform as many optimizations.
  • Limited Interactivity
    MLton is optimized for batch processing and does not provide interactive development features like a REPL (Read-Eval-Print Loop), which can be a downside for some developers used to interactive programming environments.
  • Platform Availability
    While MLton supports several platforms, its availability may not be as widespread as other more commonly used programming environments, which could limit use in certain contexts.

  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / over 1 year ago
  • 4th year, about to fail an entire semester's worth of classes.
    Get more involved. Look into internships and junior SWE positions to get a sample of what you'd be applying for once you graduate. Solve coding challenges, start working on a portfolio of your personal works. I recommend codewars.com for coding challenges, it's fun. Source: over 1 year ago
  • Beginner with C++ looking for direction
    I'd recommend to play around with some basic coding challenges on leetcode.com or codewars.com. If the course prepared you well you won't find this useful, but playing around with them will make sure that you are comfortable with basics such as loops, if statements etc. Source: almost 2 years ago
  • Can you guys recommend an efficient way to learn in advance IT para sa mga walang alam?
    I would advise for you to start with Python, it's a beginner-friendly programming language and it'll help with wrapping your mind around things. Play around with it, perhaps do some katas on CodeWars and you'll be set. Source: almost 2 years ago
  • How do I develop programming logic?
    There is a website called codewars.com where you can select problems of varying difficulty for the language you need. It is very helpful for learning. Source: almost 2 years ago

  • Simple JSON parser in c++, rust, ocaml, standard ml
    Once I got the parser ready in OCaml, I thought I port it to Standard ML, since it belong to the same ML language family. I was also curious on how well mlton could optimise it. The language lacks custom let bindings, so I resorted to use Result.bind manually. This makes code much less readable and more verbose. The standard library also lacks result type, so I had to come up with my own simple implementation.... - Source: dev.to / over 2 years ago
  • Ante: A low-level functional language
    If you’re fine with tracing GC (which depends on the situation, of course), Standard ML is a perfectly boring language (that IIUC predated and inspired Caml) and MLton[1] is a very nice optimizing compiler for it. The language is awkward at times (in particular, the separate sublanguage of modules can be downright unwieldy), and the library has some of the usual blind spots such as nonexistent Unicode support... - Source: Hacker News / almost 3 years ago
  • Write your own programming language in an hour with Chumsky
    Unfortunately, I haven't found a ton of "easily-digestible" and, at the same time, comprehensive guides on compiling functional languages. Generally you'll find a mix of blog posts/class notes/papers covering a single step. Some resources I like: - Andrew Kennedy's 2007 paper Compiling with Continuations, Continued [1]. This one is the most clear IMO - Andrew Appel's Compiling with Continuations book... - Source: Hacker News / about 3 years ago
  • Why are imperative programs considered faster than their functional counterparts?
    More broadly, they can be fast even without such extensions if they aggressively pursue optimization opportunities afforded by static typing, like MLton for example, but that also impacts compilation performance negatively. Source: over 3 years ago
