Why need $$ double

const drink = ${flavor} ${type}: $${price}

for this last line, I can get it to display correctly with just one $

app.js
const flavor = "Blueberry";
const type = "Smoothie";
const price = 4.99;
const drink = `${flavor} ${type}: ${price}`

Hi Calvin Luo

Are you sure it displays "properly"? 🤔

You need two $ so a dollar sign will show up in the finished string. The first one you put will be the one in the string, while the 2nd one denotes a template literal. If you only use one, you get 4.99, whereas when you use two, you get $4.99.

Keep Coding! :) :dizzy:
