PureScript VS Purify

• Strong Typing
  PureScript features a robust type system with advanced type inference, which can help catch errors at compile-time and increase code reliability.
• Immutability
  PureScript promotes immutability by default, leading to more predictable and maintainable code, especially beneficial in concurrent applications.
• JavaScript Interoperability
  PureScript can interoperate seamlessly with JavaScript, allowing developers to leverage existing JavaScript libraries and tools within PureScript projects.
• Functional Programming
  PureScript is a purely functional language, offering all the advantages of functional programming such as higher-order functions, and a strong emphasis on functions as first-class citizens.
• Safety and Predictability
  The language ensures safer and more predictable code by eliminating certain classes of runtime errors through compile-time checks.

Possible disadvantages

• Smaller Community
  Compared to more mainstream languages, PureScript has a smaller community, which can lead to fewer resources and libraries available.
• Learning Curve
  PureScript's focus on functional programming and its type system can present a steep learning curve for developers unfamiliar with these concepts.
• Tooling and Ecosystem
  The tooling and ecosystem around PureScript may not be as mature or extensive as those of more established languages, which can impact productivity.
• Performance Overheads
  Due to its focus on immutability and the abstraction over JavaScript, some use-cases might face performance overheads compared to plain JavaScript.
• Complexity in Interop
  Despite its capability to interoperate with JavaScript, managing the integration between PureScript and JavaScript can sometimes be complex and error-prone.

• Open Source
  Purify is available on GitHub, making it accessible for developers and allowing for community collaboration and transparency in development.
• Customizability
  Users can modify and adapt the code to suit their specific needs or use cases due to its open-source nature.
• Community Support
  Being hosted on GitHub, Purify can benefit from the input and solutions provided by a broad community of developers.

Possible disadvantages

• Lack of Official Support
  As an open-source project, Purify may lack formal customer support, which can be an issue for some users seeking professional assistance.
• Potential for Limited Documentation
  Open-source projects often have less comprehensive documentation, making it challenging for new users to understand and implement the solution effectively.
• Variable Update Frequency
  The development and update cycle of open-source projects can range from active to infrequent, potentially affecting the tool's reliability and security.
