Was there code splitting in the project? Which bundler was used?

Yes, code splitting was used in the project to optimize loading and improve performance. Webpack was used as the bundler, which allows dynamically loading parts of the application as needed, reducing the initial bundle size.

Example of dynamic import with Webpack:

import(/* webpackChunkName: "myChunk" */ './myModule').then(module => {
  module.doSomething();
});

This enables splitting the application into separate chunks that are loaded only when necessary.
