Why is the bundle size in the Counter example from Samples in Redux 2Mb?

Question

JavaScript

I compiled a bundle for the Counter example in the Redux sources - it weighs 2 mb!
Are these all these tiny Redux apps???

Answer 1

In a dev environment, with sourcemaps and without minification, any application weighs so much.
In production mode, without sourcemaps and with minification, the weight will be several times less.

Answer 2

compiled for production environment webpack -p
