What are the downsides of using modular JavaScript?

While modular JavaScript offers many benefits, there are some downsides to consider. One major issue is the increased complexity in project setup and configuration. You may need to manage multiple files and dependencies, which can lead to a steeper learning curve for new developers.

Are there performance issues with modular JavaScript?

Yes, there can be performance issues, especially if modules are not optimized. Loading multiple modules can lead to increased load times, and if not managed properly, it can result in larger bundle sizes.

How does it affect code readability?

Modular JavaScript can improve code readability by organizing code into smaller, manageable pieces. However, if overused or poorly structured, it can lead to fragmentation, making it harder to follow the overall flow of the application.

What about compatibility with older browsers?

Modular JavaScript often relies on modern features that may not be supported in older browsers. This can necessitate the use of polyfills or transpilers, adding to the complexity of the development process.

Is there a way to mitigate these downsides?

Yes, you can mitigate these downsides by using build tools like Webpack or Rollup to optimize your modules, ensuring proper documentation, and adhering to best practices in module design.
