问题 The Problem create-react-app initializes a repository where babel-loader is installed as an older version than needed. LOG: There might be a problem with the project dependency tree.

However, a different version of babel-loader was

问题 How can we compile modern JavaScript into backwards-compatible JavaScript bundles that can be used with Internet Explorer 11 (ie11)?

问题 I'm trying to configure webpack (5) with babel, using babel-loader to transpile to ES5. Unfortunately, the output is not consistent. Basically, it's divided into two parts: Some polyfills: My code: As you can see, the first part contains arrow functions, and the second one not. I've tried to add @babel/plugin-proposal-class-properties and @babel/plugin-transform-arrow-functions to my .babelrc file, but the class-properties is missing (with debug enabled). I must admit, I'm not sure that the
