How Dynamically link assets in Laravel 5

I'm new to Laravel 5 i while searching over internet i for some basic concepts i found that in Laravel we can link assets dynamically i didn't understand how can we link them dynamically.

How can we know that an asset is used in certain point and include it in the view.

As per my knowledge i'm writing all the assets in one blade template and extending in views.

example.blade.php

custom view.blade.php

@extends('example)

But how come this do Dynamically?
