What is incremental compilation and how does it work in different programming languages?

Incremental compilation is a technique that allows a compiler to compile only the parts of a program that have changed, rather than recompiling the entire codebase. This can significantly speed up the build process, especially in large projects.

Can you give examples of languages that support incremental compilation?

Sure! Languages like C++, Java, and Rust support incremental compilation. For instance, Rust uses a build system called Cargo that efficiently compiles only the modified parts of the code.

What are the benefits of using incremental compilation?

The main benefits include faster build times, improved developer productivity, and reduced resource usage. It allows developers to see changes more quickly without waiting for long compilation times.

Are there any downsides to incremental compilation?

Yes, there can be downsides such as increased complexity in the build system and potential issues with stale dependencies, which might lead to unexpected behavior if not managed properly.
