const drink = '${flavor} ${type}: $${price}' ; why are we using two $$ for price?

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

why are we using two $$ for price?

app.js 
const flavor = "Blueberry";
const type = "Smoothie";

Hi Nasra Iid,

The reason for the double $, is because in template literals the $ follow by a { represents the start of a template variable. The first $ represents the symbol for dollar (USD). Without it, the phrase returned would be “Blueberry smoothie: 4.99” instead of “Blueberry smoothie: $4.99”.

Hope that makes sense. Good question.
