Issue
Hi everybody I am trying to follow a video lesson of Angular.js I added ng-app at the html tag, the ng-controller in the body to use the controller but I see all the {{elements}}. (If I remove the ng-controller, the input field works fine, but when I try to add the ng-controller, starts the problems... in the following code I should show only a list of authors

The file app.js, contains the list of author (only one in my example) is the following:
var myApp = angular.module('MyApp', []); // no dipendenze []
myApp.controller('MyController', function MyController($scope) {
$scope.artist = {
"name":"Emilio Alfieri",
"shortname":"Draco",
"study":"Ing. Informatica",
"bio":"Nato a Roma il 7/05/1987, si è sposato il 19 Agosto 2020 in Indonesia.Adora la chitarra e i computers."
}
}); //$scope è come una variabile globale
I receive the following error: Uncaught Error: [$injector:modulerr] I really followed all the instruction I have seen in the video. What's my mistake?
Thank you very much!

Solution
You made a spelling mistake of module name.
Replace var myApp = angular.module('myApp', []);
instead of
var myApp = angular.module('MyApp', []);
var myApp = angular.module('myApp', []);
myApp.controller('MyController', function($scope) {
$scope.artist = {
"name":"Emilio Alfieri",
"shortname":"Draco",
"study":"Ing. Informatica",
"bio":"Nato a Roma il 7/05/1987, si è sposato il 19 Agosto 2020 in Indonesia.Adora la chitarra e i computers."
}
