How does modular programming in JavaScript affect performance?

How does modular programming in JavaScript affect performance?

Modular programming can enhance performance by allowing for better code organization, reusability, and easier maintenance. It helps in loading only the necessary modules, which can reduce the initial load time.

Can you explain how tree shaking works in this context?

Tree shaking is a technique used in modern JavaScript bundlers to eliminate unused code. When using modular programming, only the modules that are actually used in the application are included in the final bundle, which improves performance.

What are some best practices for modular programming in JavaScript?

Some best practices include keeping modules small and focused, using clear naming conventions, and ensuring that modules have minimal dependencies on each other.

Are there any performance drawbacks to modular programming?

Yes, if not managed properly, modular programming can lead to performance issues such as increased load times due to too many small modules or excessive dependencies. It's important to balance modularity with performance.
