An issue has occurred while utilizing Angular

I'm diving into the world of Angular and encountering some errors as I try to execute this code.

  1. An unexpected token is causing trouble. A constructor, method, accessor, or property was expected.
  2. The left side of a comma operator seems to be unused with no side effects.
  3. There appears to be a missing declaration or statement in the code.
export class AppComponent {
  var app = ('app', ['ngAnimate'])

  app.controller('mainCtrl', function($scope) {
    $scope.boxes = [{
      name: 'Friends',

    }, ];

    $scope.selected = [];
    $scope.selectBox = function(item, position) {
      $scope.selected = [{
        item: item,
        position: position
      }];
      $scope.$apply();
    }
    $scope.clearSelection = function() {
      $scope.selected = [];
    }
  })
}

Answer №1

Your class has a keyword at the beginning: var. Utilize var to assign variables within a class and properties outside of it.

In Node.js, declare a property using the this. keyword in the constructor or outside of it (like in TypeScript).

An example in Node.js:

class AppComponent {
  constructor() {
    this.app = ('app', ['ngAnimate'])
  }
}

The code you provided seems questionable; the structure may not be valid upon inspection.

Rather than declaring app.controller() in the primary scope of the class, it's typically inside a method or as a method declaration.

Please try making adjustments based on the above information, and let me know if there are other issues that need fixing (likely with the following line).

I'll also delve into AngularJS to ensure I'm offering accurate advice, given my experience lies more with Angular 6+ which has differing syntax.

EDIT: Providing a source for the code you're learning from will greatly enhance your chances of receiving assistance.
