What is the difference between Section and Stack in Blade?

I might be mistaken, but the difference is not only semantically, but in behaviour as well. With @push you append as many times as needed to a stack, while (by default) you may fill @section only once in your views. In some situations this comes in handy when you need to add content from different locations across your template files or in loops:

index.blade.php:

@extends('master')

...  

@for ($i = 0; $i < 3; $i++)

  @push('test-push')
    <script type="text/javascript">
    // Push {{ $i }}
    </script>
  @endpush

  @section('test-section')
    <script type="text/javascript">
    // Section {{ $i }}
    </script>
  @endsection

@endfor

master.blade.php

    @stack('test-push')
    @yield('test-section')
</body>

result:

    <script type="text/javascript">
    // Push 0
    </script>
        <script type="text/javascript">
    // Push 1
    </script>
        <script type="text/javascript">
    // Push 2
    </script>
    <script type="text/javascript">
    // Section 0
    </script>
    </body>

Stack is someway appropriate for scripts , with stack you can Append as much as you need .

@push('scripts')
    <script src="/example.js"></script>
 @endpush

Append …

<script>
@stack('scripts')
</script>

As you can see the script's stack will be appended under the script tag of example js. So you can push special scripts for each view.
