I was wondering about the differences between angular2.js and angular2.dev.js, of course there are more files like: router.dev.js and router.js and more, my question is why there are 2 versions and what is the differences between them?

angular2.dev.js uses global.Zone.longStackTraceZone = require('../zones/long-stack-trace.js') via zone.js for showing long stacktrace for angular exceptions to help with your development.

Thank you, now I understand.
There are actually three versions of angular2.js along with three files for each dependency. There is the regular prod version of each (angular2.js), a minified prod version (angular2.min.js) and a development version (angular2.dev.js). Check out this link to see how the files can be bundled: Bundles, their content and usage scenarios

So as per @Bonneville's useful link the pattern would be, during development as "SystemJS loader user", to reference from the index.html the dev scripts:
- node_modules/angular2/angular2.dev.js,
- node_modules/angular2/router.dev.js and
- node_modules/angular2/http.dev.js
and then for production to swap in the minified scripts:
- node_modules/angular2/angular2.min.js,
- node_modules/angular2/router.min.js and
- node_modules/angular2/http.min.js
