Fourth-week Javascript

Hi Everyone!! It has been 4 weeks since started doing Javascript. the topics which I covered during this week are the following.

1)Express js
2)MVC(Model-View-Controller)
3)Middleware
4)Template engine and Ejs file
5)Cookies
6)Session

This week was a bit overwhelming for me. I think it is still unsure whether I got these concepts well or not. I am thinking to stick these concepts for the upcoming week too and make sure I got these concepts, then I will move forward.

Thanks for reading!!!
