Debuggers don't work fine. something wrong with the build system.

Debuggers don't work fine, something wrong with the build. if I post the code from `src` into say a `create-react-app` package though debuggers works fine.

By debugger I mean the keyword `debugger` that we use in javascript to debug. Webpack has issues with chrome, but than again why does `create-react-app` work fine and `react-slick` does't.
