this reference is not working

[remote pewter]

export class AuthController {
  constructor(public readonly authService: AuthService) {}

  LoginUser(req: Request, res: Response) {
    console.log("test", this.authService.LoginUser("text"));

    this.authService
      .LoginUser("test")
      .then((result) => res.json(result))
      .catch((error) => console.log(error));
  }

  RegisterUser(req: Request, res: Response) {
    res.json("Auth Register");
  }
}

``` why this code doesn't work for loginUser but when i do a arrow function "this" gets the reference?

[rose ingot]

if you dereference the method, the binding gets lost. what method is having the issue exactly?

(btw, in ts, methods are in camelCase by convention, rather than PascalCase, just in case you weren't aware)

[bitter hearth]

this in a method is the object that the method was called on. So

const ac = new AuthController
ac.LoginUser() // this is ac
const loginUser = ac.LoginUser
logicUser() // this is null or something like that
const obj = {
  loginUser: ac.LoginUser
}
obj.loginUser() // this is obj

If you use an arrow function instead then it keeps this as the instance it was created in, no matter what. (This is largely we have => functions, it's not just syntax shortcut)
