It's the best! Now, not only webpack, but also the version has changed a lot, It's hard to apply it to new development that wants to use actual webpack 5 (there are third-party libraries that don't support webpack 5, so there are still cases where webpack 4 is used..) Because it's a lecture that teaches the basics and principles, I think it's a lecture that will be helpful when using webpack version 5 if you just google it a little. Thank you for the great lecture. I learned a lot ^^
