I try to CRUD Cookbook. And I found two points to fix.
(※1. line 19, 2. line 45)
Can I fix it?

[AS-IS]
var (
users = map[int]*user{}
seq = 1
)
[TO-BE]
var (
users = map[int]*User{}
seq = 1
)

[AS-IS]
func updateUser(c echo.Context) error {
u := new(user)
if err := c.Bind(u); err != nil {
return err
}
id, _ := strconv.Atoi(c.Param("id"))
users[id].Name = u.Name
return c.JSON(http.StatusOK, users[id])
}
[TO-BE]
func updateUser(c echo.Context) error {
u := new(User)
if err := c.Bind(u); err != nil {
return err
}
id, _ := strconv.Atoi(c.Param("id"))
users[id].Name = u.Name
return c.JSON(http.StatusOK, users[id])
}
