so let's take it by parts : 1-he wanted to userName have a uppercase of the id => var userName = id.toUpperCase(); 2-he want the name to be 23188XTR#SMITH so we need to add # to our variable => var userName = id.toUpperCase() + "#"; then he want a uppercase of the last name after that => var userName = id.toUpperCase() + "#"+ lastName.toUpperCase();
