What are the differences between C++ modules and headers?

What are the differences between C++ modules and headers?

C++ modules are a newer feature that provide better encapsulation and faster compilation compared to traditional headers.

Can you explain how modules improve compilation times?

Modules allow for precompiled interfaces, reducing the need to recompile code that hasn't changed, thus speeding up the build process.

Are there any downsides to using modules?

Yes, modules can have a steeper learning curve and may not be supported in all compilers yet.

Which one should I use for a new project?

If your compiler supports it, using modules is recommended for better performance and organization.
