What is the difference between tree shaking and code splitting?

What is the difference between tree shaking and code splitting?

Tree shaking is a technique used to eliminate dead code from your final bundle, while code splitting is about breaking your code into smaller chunks that can be loaded on demand.

Can you explain how tree shaking works in JavaScript?

Sure! Tree shaking works by analyzing the import/export statements in your code and removing any unused modules during the build process.

What tools can I use for tree shaking?

Popular tools for tree shaking include Webpack, Rollup, and Parcel, which all support this feature to optimize your bundles.

Is code splitting beneficial for performance?

Yes, code splitting improves performance by reducing the initial load time, as only the necessary code is loaded at first.

Can I use both techniques together?

Absolutely! Using both tree shaking and code splitting together can significantly enhance your application's performance by minimizing the bundle size and loading only what's needed.
