Good afternoon
I'm following the socket.io start tutorial and it's all working, but I do not understand why jquery only works if calling the script in html
I tried to install by npm and it does not work (the message does not log in)
I thought that package.json was right so I did not have to call the script in html
Or to use by npm I should have taken the html script by putting in a file the part?
Can you explain better how this works?

form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
