/**
 * 1 - Make all functions public - add [public] keyword before each one
 * 2 - use camelCase name syntax [allData] not [AllData]
 * 3 - leave some spaces between the variable name and the value
 * 4 - you can use the Validator facade to catch the errors or validate your comming request before doing the logic
 * 5 - you cant return dd() [ dd() for the development things ] instead return response()->json(array $data);
 * 6 - use request advantage to detrmine if that request is a POST, GET, or PUT request not in the Controller
 *     such as this Route::put('/url', 'SomeController@editUser');
 *                  Route::post('/url', 'SomeController@updateUser');
