Hi Tseng, The back-ticks (those angled single-quote marks) indicate that this is a "template literal". It's a feature in ES6 that allows you to write multi-line strings and embed variables into the string like you see here. That's actually what the ${username} is: it's how to embed the variable, username, into the template literal string.
