What is tree shaking and how does it help with bundle size?
Tree shaking is a technique used in JavaScript bundlers to eliminate dead code. It helps reduce bundle size by removing unused exports from your modules.
Can you explain how tree shaking works in practice?
Sure! When you import modules, the bundler analyzes the code to determine which parts are actually used. It then excludes the unused code from the final bundle.
Are there any specific tools that support tree shaking?
Yes, popular tools like Webpack, Rollup, and Parcel support tree shaking. They optimize the bundle size by leveraging static analysis.
What are the benefits of reducing bundle size?
Reducing bundle size improves load times, enhances performance, and provides a better user experience, especially on mobile devices.
