How can I show a dollar sign before a number in JavaScript to make the output look nicer?

Hello James, really nice question.

In JavaScript, the easiest way to make the output look cleaner with a dollar sign is to format it as a string. A very common way to do that is with a template literal (using backticks `):

let costPrice = 25;
let sellPrice = 35;

let profit = sellPrice - costPrice;

console.log(`Profit: $${profit}`);

What’s happening here:

• The backticks let you write a string with embedded expressions.

• ${profit} is replaced by the actual value of profit.

• The $ before it is just a normal character in the string, so it shows up exactly as you’d expect.

You could also do it with string concatenation:

console.log("Profit: $" + profit);

Both work, but template literals are usually cleaner and easier to read, especially as the text gets longer.

If you have further questions, I'm here to help.
