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.

Objective-C features and specs

• Mature Language
  Objective-C has been around since the 1980s, which means it has a long history of use in Apple's ecosystem, leading to a wealth of documentation, resources, and a stable, well-understood language.
• Dynamic Runtime
  Objective-C's dynamic runtime allows for a high level of flexibility, such as dynamically loading classes and methods, which can be beneficial in certain programming scenarios requiring runtime adjustments.
• C Compatibility
  Objective-C is a superset of C, which means it retains all functionalities of C, allowing low-level manipulation and the ability to integrate existing C libraries easily.
• Rich Library Support
  With strong ties to Apple's ecosystem, Objective-C has extensive support for native libraries like Cocoa and Cocoa Touch, enabling efficient iOS and macOS application development.
• Proven Track Record
  Many successful applications have been built using Objective-C, illustrating its capabilities in handling complex and large-scale applications.

Possible disadvantages of Objective-C

• Complex Syntax
  The syntax of Objective-C can be verbose and complex compared to modern languages, leading to a steeper learning curve for new developers.
• Limited Adoption Outside Apple Ecosystem
  Objective-C is primarily used within Apple's ecosystem, limiting its applicability and adoption in other platforms or general software development.
• Lack of Modern Features
  Compared to newer programming languages like Swift, Objective-C lacks some modern programming features such as type safety, which can lead to more runtime errors.
• Memory Management
  Although ARC (Automatic Reference Counting) has simplified memory management, developers still have to be conscientious about memory usage compared to simpler garbage-collected environments.
• Performance Considerations
  The dynamic nature of Objective-C can introduce performance overhead, as dynamic message sending is slower compared to static method calls in languages like Swift.
