问题
In some laravel examples I've seen assets being called like this:
<link rel="icon" type="image/png" href="{{ asset('icons/favicon-32x32.png') }}" sizes="32x32">
What is the advantage of using that method as opposed to doing this?
<link rel="icon" type="image/png" href="icons/favicon-32x32.png" sizes="32x32">
回答1:
If you do the latter, the URLs will not work when you're on any URL that includes a forward slash. E.g. not using asset will appear to work fine if you're on the homepage, but if you were on /search/results or whatever, the URLs won't be correct (as it'll be looking for /search/icons/favicon-32x32.png).

It helps you to generate a valid URL for your assets.
If you use asset('icons/favicon-32x32.png'), it will always create application related URL's irrespective of the position of the installation folder of your app in the server.
For example, if your application is hosted in a subfolder instead of the root directory, if you use asset method, laravel will create the related path for the asset.
