The following describes how to use webpack with babel to convert es6 to an ultra-simple instance of es5 and webpackes5. Today, I got started with webpack. The first time I used webpack for transcoding, it turned out to be a bit confusing. Haha. The process is attached below Create folders and initialize them. First, install webpack globally. npm install webpack --save-dev Then install babel npm install --s
