Working my way through Javascript basics and I have a question

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

// Blueberry Smoothie $4.99

Question why do you need two $ before price?

Hi Matthew,

The syntax for a template literal is ${}. If you don’t have the $ immediately preceding the {} (braces) then Javascript doesn’t know that the contents between the braces should be interpreted/evaluated.

So if you want to show a dollar sign, you need to place a second dollar sign before the one that symbolizes the beginning of a template literal.

With only one $, you’d end up with the following:

// Blueberry Smoothie 4.99
instead of
// Blueberry Smoothie $4.99

Hope that helps
