JavaScript JavaScript Basics (Retired) Storing and Tracking Information with Variables Using String Methods

How do you add together strings?

I am unsure how to ad the 'id', #, and 'lastName' together to get the final product while using the .toUpperCase

var id = "23188xtr";
var lastName = "Smith";

var userName


console.log "usernName" = "id+#+lasName".toUpperCase();
  <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

var id = "23188xtr"; var lastName = "Smith";

var userName = id + lastName;

Look at it as 1 + 2 = 3 (or 3 = 1 + 2)
