How to get PHP Timestamp on JS

Use Carbon.

If it's already a Carbon datetime instance (like the model timestamps created_at and updated_at, you can do this:

$dt->format('Y-m-d H:i:s');

If it's not a Carbon instance, try this:

Carbon::parse($timestamp)->format('Y-m-d H:i:s');

Use Moment ...

@arukomp I should have provided more info

Here is my JS:

document.getElementById("date").value = i-need-to-fill-this-part;

Not sure how i should continue from here.

Forget Carbon. Use Moment if you want to muck about with dates in JS.

Nice. Moment worked just fine. Thanks
