What is the difference between JavaScript bundling and transpiling?

JavaScript bundling is the process of combining multiple files into a single file to reduce the number of HTTP requests. Transpiling, on the other hand, involves converting code from one version of JavaScript to another, often to ensure compatibility with older browsers.

Can you give me examples of tools used for bundling and transpiling?

Sure! For bundling, popular tools include Webpack and Rollup. For transpiling, Babel is widely used to convert modern JavaScript into a version that older browsers can understand.

Why is bundling important for web performance?

Bundling is important because it reduces the number of files the browser has to download, which can significantly improve load times and overall web performance.

Are there any downsides to bundling?

Yes, one downside is that if not done correctly, bundling can lead to larger file sizes, which may negatively impact performance. It's important to balance the number of requests with the size of the bundle.
