How to fix The name "ViewBag" doesn't exist in file javascript

Question

I have a issue in Visual Studio 2017. I want to get data from the controller in the Razor file. So the value doesn't exist in the file.

The code and problem is below.

Controller:

public IActionResult Product(int? product)
{
    if (product == 0)
    {
        return RedirectToAction("index", "home");
    }
    else
    {
        ViewBag.product = product;
        return View();
    }
}

scripts:

@section Scripts{
    <script>
        var pr = @ViewBag.product;
    </script>
}

Error:
