Can you explain how tree shaking works in Rollup?
Sure! Tree shaking is a feature in Rollup that eliminates unused code from your final bundle, making it smaller and more efficient.
How does Rollup determine which code is unused?
Rollup analyzes the import and export statements in your modules. It builds a dependency graph and removes any code that isn't referenced.
Does tree shaking work with all JavaScript modules?
Tree shaking works best with ES6 modules because they have static structure, allowing Rollup to analyze dependencies effectively.
What are some best practices for effective tree shaking?
To maximize tree shaking, use ES6 modules, avoid dynamic imports, and ensure your code is modular and well-structured.
