Encountering nonsensical compilation errors when using console.log() in Angular version 13.0.1

While working on a tutorial from Udemy, I encountered some unexpected errors:

Unexpected keyword or identifier.
,
Member 'console' implicitly has an 'any' type.
,
Unexpected token. A constructor, method, accessor, or property was expected.
,
'log', which lacks return-type annotation, implicitly has an 'any' return type.
, Identifier expected.. On line 10 of my code is this snippet: console.log('example');

Could someone provide insight into what might have gone wrong here?

Edit: Below is the code snippet in question:

import { Injectable } from '@angular/core';

@Injectable({
  providedIn: 'root'
})
export class HardcodedAuthenticationService {

  constructor() { }

  console.log('example');

  authenticate(username: any, password: any) {
    if (username !== '' && password !== '') {
      sessionStorage.setItem('authenticatedUser', username)
      return true;
    }
    return false;
  }

  isUserLoggedIn() {
    let user = sessionStorage.getItem('authenticatedUser');
    return !(user === null)
  };
}

Answer №1

In order for console.log() to function correctly, it must be contained within a function or method. Due to the nature of the log command, it cannot be executed independently outside of a function or method.
