I studied when Webpack 5 came out, so I learned additional things about the parts that changed because the versions didn't match, but the basic concepts that you teach us are unchanged, and I felt that I understood the front-end development environment rather than Webpack, and I would like to express my gratitude. As you said in the last summary, technology is developing rapidly, and it was a good lecture that made me feel that it is really important to accurately recognize the concepts and develop the ability to adapt to changed technology. I highly recommend it if you want to understand and use the front-end development environment.
