What are the differences between popular JavaScript bundlers?

What are the main differences between Webpack, Rollup, and Parcel?

Webpack is highly configurable and great for complex applications, while Rollup is optimized for libraries and offers tree-shaking. Parcel is zero-config and user-friendly, making it ideal for smaller projects.

Which bundler is the best for a large-scale application?

For large-scale applications, Webpack is often the best choice due to its extensive plugin ecosystem and flexibility.

What about performance? How do they compare?

In terms of performance, Rollup generally produces smaller bundles due to its tree-shaking capabilities, while Webpack can be optimized with various configurations.

Can you give me an example of a project setup for each?

Sure! For Webpack, you would set up a webpack.config.js file. For Rollup, you'd create a rollup.config.js, and for Parcel, you just need to run parcel index.html without any config.
