I have a .blade.php file that was generated by Laravel and it contains the following line
{{-- --}}
What are the double-curly-double-dashes?
Is it a comment?

{{-- This comment will not be present in the rendered HTML --}}

Yes, this the syntax for a comment in the blade template. It will not be included in the HTML that is generated when the view is called.
