What is bundle size optimization and why is it important?

Bundle size optimization refers to the process of reducing the size of your JavaScript bundles to improve load times and performance. It's important because smaller bundles lead to faster page loads, better user experience, and improved SEO.

How can I optimize my bundle size?

You can optimize your bundle size by using techniques like code splitting, tree shaking, and minification. Tools like Webpack and Rollup can help with these processes.

What is code splitting?

Code splitting is a technique that allows you to split your code into smaller chunks, which can be loaded on demand. This means that users only download the code they need for the current page, reducing the initial load time.

Can you explain tree shaking?

Tree shaking is a term used in JavaScript bundlers to describe the process of removing unused code from your final bundle. It helps in reducing the bundle size by eliminating dead code.
