##Chapter 3: A gentle introduction to routing, controllers, and views
Folder structure


Element
Path


Models:
appname/app/modelname.php


Controllers:
appname/app/Http/Controllers/controllername.php


Views:
appname/resources/views/viewname.blade.php


Routes (Rails_eq: routes):
appname/routes/web.php


Config/App (Rails_eq: gemfile):
appname/config/app.php


Environment config:
appname/.env


Declaring a route
Method 1:
Return text when this address is visited
Route::get('/contacts', function(){
  return "Contact Us";
});
Method 2:
Return custom view when this address is visited
Route::get('/', function(){
  return view('welcome');
Method 3:
Return controller/view pair
Route::get('/', 'WelcomeController@index');
##Chapter 4: Passing Data to Views

Supports
      make:auth                                                   
      make:command                                                
      make:controller                                             
      make:event                                                  
      make:job                                                    
      make:listener                                               
      make:mail                                                   
      make:middleware                                             
      make:model                                                  
      make:notification

      make:provider                                               
      make:request                                                
      make:seeder                                                 
      make:test

                                  'last' => 'Doe'
                                  ]);
Method 3:

a) As an array
$data=[]
$data['first'] = 'Douglas';
$data['last'] = 'Doe';
return view('pages.about', $data);
b) By Compact function
$first = 'John';
$last = 'Doe';
return view('pages.about', compact('first', 'last'));
