在php文件上打印到控制台

I'm using Visual Studio to do tests on some code. The file is a .blade.php. I'm trying to print the elements in an array in an for loop by doing this:

for (var item in data) {
    console.log(item) }

Nothing shows up in my console when I do this. How can I see what items are in data?

May be you are missing script tag

<script>
for (var item in data) {
    console.log(item) }
</script>
