pass parameter to view laravel

We can pass data to view simply from controller or from web.php as well here is a example

Route::get('/', function () {
    return view('greeting', ['name' => 'Jones']);
});

Now in case you need to pass data from controller. it will look like this

Route::get('/', SomeController@someFunction);

Inside "Some Controller" here we have someFunction looks like this

public function someFunction(){
    return view('greeting', ['name' => 'Jones']);  
}

or 

public function someFunction(){
    return view('greeting')->with('posts' , $posts);  
}

Hope this helps
