index.pug For Each User in Users declaration and express route

Hi there

I have a question regarding how the declaration in the views folder for the index file is being used.

I see that the index.pug file has a "user" in singular that I cannot relate directly to the users const variable declaration in app.js file and with the users.users Json data attribute from the JSON file.

body ul each user in users li(class="user") i(class="material-icons") account_box h3 #{user.name} p #{user.username} p #{user.bio}

Thanks in advance for any feedback given to this server.

Sorry nobody got around to answering this question earlier, but this portion of the index.pug file is what allows you to reference the user variable:

      each user in users 
        li(class="user")
          i(class="material-icons") account_box
          h3 #{user.name}
          p #{user.username}
          p #{user.bio}

      each user in users

In this snippet from the file, each is a forEach method. It is cycling over each object in users and performing the action of creating a list item for each of them. Hope this helped!
