Hi Ashish,
Thanks for your interest in Essential JS 2.
Query: Is is possible to see the sources?
Yes, it is possible to see the sources for showcase applications. We will publish the source code of Showcase applications in Github and this will be rolled out within a week.
We will let you know once it is published until then we appreciate your patience.
Please let us know if you have any concerns.
Regards,
Sridurgha U
