Why my code is running differently , it shows error

const strings = ['1','2','3','4','5']; const priceToDollars = price => '$${price.toFixed(2)}'; const displayPrices = prices.map(priceToDollars); console.log(displayPrices);

There's a few issues to fix:

  • the code calls .map on "prices", but no identifier named "prices" has been defined
  • the array named "strings" is never used, should that be "prices"?
  • but if so, "toFixed" is not a method for strings — it only works on numbers
  • a template string must be enclosed by accents (`) instead of apostrophes (')
