What are the differences between Rollup and other bundlers?

Rollup is a module bundler specifically designed for JavaScript libraries and applications. Unlike other bundlers like Webpack, Rollup focuses on ES modules and tree-shaking, which helps eliminate dead code and reduce bundle size.

Can you explain tree-shaking in more detail?

Sure! Tree-shaking is a feature that allows Rollup to analyze the code and remove unused exports. This results in smaller bundle sizes, as only the necessary code is included in the final output.

What are some advantages of using Rollup over Webpack?

Some advantages of Rollup include simpler configuration, better performance for libraries, and more efficient code output due to its focus on ES modules.

Are there any downsides to using Rollup?

Yes, while Rollup is great for libraries, it may not be the best choice for complex applications that require extensive plugin support, which Webpack excels at.
