Possible disadvantages

• Fees
  ProPay's fee structure can be complex and might be higher than some competitors, which could be a drawback for small businesses.
• Limited International Presence
  ProPay primarily operates in the United States, which might not be suitable for businesses with significant international transactions.
• Account Reserves
  Some users report that ProPay requires reserve balances to mitigate risk, which could potentially tie up funds for businesses.
• User Interface
  The user interface of ProPay's platform can be less intuitive compared to some modern competitors, which might result in a steeper learning curve.
• Withdrawal Times
  The time it takes to transfer funds from ProPay to a bank account can be longer than expected, which can affect cash flow for businesses.

• Improved Code Organization
  Modular JavaScript allows developers to break down code into smaller, manageable modules. This enhances code readability and maintainability by organizing related functionality together.
• Code Reusability
  Modules encourage reusability by allowing the same piece of code to be used across different projects or multiple areas of the same application, reducing redundancy.
• Scalability
  As the application grows, managing code becomes easier with modular JavaScript. Each module can be developed, tested, and maintained independently, making the codebase more scalable.
• Encapsulation
  Modules provide encapsulation, preventing variables and functions from polluting the global namespace. This reduces the risk of naming conflicts and bugs.
• Improved Testing
  With code organized into discrete modules, writing unit tests becomes more straightforward. Each module can be tested individually, leading to more reliable and maintainable tests.

Possible disadvantages

• Increased Complexity
  Introducing modularity can add complexity to the build process, as it often requires module loaders or bundlers (like Webpack or Browserify) to manage dependencies.
• Overhead
  For smaller projects, using a modular approach might be overkill, introducing unnecessary overhead in terms of setup, configuration, and code management.
• Learning Curve
  Developers unfamiliar with modular JavaScript may face a learning curve, especially when dealing with module patterns, loaders, and bundlers.
• Dependency Management
  Relying on multiple modules can lead to complex dependency chains, making it challenging to track and resolve dependencies across different modules.
• Performance Overhead
  Modular JavaScript can introduce performance overhead if not managed properly, such as loading many small modules individually, leading to increased HTTP requests.
