Using forEach, turn the number strings from the stringPrices array into floats and add them all, storing the total in th

I don't know why it doesn't work?

app.js 
const stringPrices = ['5.47', '3.12', '8.00', '5.63', '10.70'];
let priceTotal = 0;

// priceTotal should be: 32.92
// Write your code below

Hi, let's breakdown your code. You are iterating over all elements in the array. Then, you store in a constant prices a parseFloat() of all elements in the array, which is not correct because we wanna parse the current item.

What you want to do is forEach item, parse this item and adds it to the totalPrice variable. Here is how I would tackle that :

const stringPrices = ['5.47', '3.12', '8.00', '5.63', '10.70'];
let priceTotal = 0.0;
stringPrices.forEach(price=>{
    const parsedPrice = parseFloat(price);
    priceTotal += parsedPrice;
});

If it helped you, please mark as best answer!
