there is problem when I use webpack-parallel-uglify-plugin, but it's OK using uglifyjs-webpack-plugin. I'm not sure it is caused by this plugin.
the problem show as below:
Uncaught Error: React is running in production mode, but dead code elimination has not been applied. Read how to correctly configure React for production: https://fb.me/react-perf-use-the-production-build at <anonymous>:21:35
@lifeng1893 Could you create an example repo that produces this issue? We've been using this plugin at Airbnb since its creation and haven't experienced this issue.
