Full Stack JavaScript Techdegree Student 102 Pointspurpose of model.put(“username”, req.cookie(“username”)) at 3min 38second of the video?
Instructor said we need to put into our model a value called “username” & will pull this cookie. Why? What is the purpose of the line model.put(“username”, req.cookie(“username”)) ?
Why is it that for post method, we did res.cookie("username",username) but for get method, we don't need req.cookie("username",username) and instead have req.cookie("username",usename) inside the parameter of model.put()?
Thank you!

Map , represents a mapping between a key and a value. More specifically, a Java Map can store pairs of keys and values. Each key is linked to a specific value. Once stored in a Map , you can later look up the value using just the key.
In this case we are using "username" as key to locate the cookie.
Why is it that for post method, we did res.cookie("username",username) but for get method, we don't need req.cookie("username",username) and instead have req.cookie("username",username) inside the parameter of model.put()?
We call the "response.cookie("username", username);" on the post method to save the username in the cookies. if you go to the developer tool and comment out the //response.cookie("username", username); in the post method you will see what happen.
