// Excluding node_modules From Being Transpiled By Babel-Loader
// One change to take into consideration,
// is that Webpacker 4 transpiles the node_modules folder with the babel-loader.
// This folder used to be ignored by Webpacker 3.
// The new behavior helps in case some library contains ES6 code, but in some cases it can lead to issues.
// To avoid running babel-loader in the node_modules folder, replicating the same behavior as Webpacker 3,
// we added the following code:
const nodeModulesLoader = environment.loaders.get('nodeModules');
