                price: priceItem,
            })

ai: Your code snippet generally looks good, but there are a few improvements and corrections that can be made for better clarity and performance. I'll also correct some issues that may arise:

1. Ensure that the `return` statement in your `parseCurrency` function properly handles cases where `parseFloat` fails.
2. The summation in the console log should correctly access the price properties of the array items.
3. You might want to use `Promise.all` if you plan to use multiple asynchronous operations for better performance.
4. Make sure to handle the case when there might be no prices available, as this could lead to errors.

Here's a revised version of your code:

```javascript
const puppeteer = require('puppeteer');

(async () => {
    const browser = await puppeteer.launch({ headless: "new" });
    const page = await browser.newPage();
    const item = "your_item_here"; // Replace with the appropriate item
    await page.goto(`https://www.ebay.fr/sch/i.html?_nkw=${encodeURIComponent(item)}&_ipg=240`);

    const itemInfoBased = await page.evaluate(() => {

        function parseCurrency(str) {
            const cleanedStr = str.replace(/\s*EUR$/, '').trim();

            const normalizedStr = cleanedStr.replace(/\u00A0/g, '');
            const numberStr = normalizedStr.replace(',', '.');

            const amount = parseFloat(numberStr);
            return isNaN(amount) ? null : amount; // Return null if parsing fails
        }

        const elements = document.querySelectorAll(".s-item__info");
        const arr = [];

        elements.forEach(e => {
            const priceItem = parseCurrency(e.querySelector(".s-item__price")?.textContent);
            if (priceItem !== null) {
                arr.push({
                    price: priceItem,
                });
            }
        });

        return arr; // Return the array instead of a JSON string
    });

    console.log(itemInfoBased);

    const total = itemInfoBased.reduce((sum, current) => sum + current.price, 0); // Initialize sum to 0
    console.log("Total price:", total);

    await browser.close();
})();
```

### Key Changes:
1. **Error Handling:** In `parseCurrency`, it now checks if `parseFloat` results in `NaN`, returning `null` in that case.
2. **Returning Raw Array:** The `itemInfoBased` now returns the raw array instead of a JSON string, simplifying the `JSON.parse` requirement.
3. **Optional Chaining (`?.`):** This helps avoid errors if `.textContent` is accessed on an undefined element.
4. **Total Calculation:** Changed how the total price is calculated by initializing the accumulator to `0`.

Make sure to replace `"your_item_here"` with the actual item you're searching for. Also, ensure you have proper error handling if you plan to run this code in a production environment.

   const total = itemInfoBased.reduce((sum, current) => sum + current.price, 0); // Initialize sum to 0
    console.log("Total price:", total);
