this is the signature definition of function loginWithPassword.

Let's break down this code:

function loginWithPassword(
    user: Object | string, 
    password: string, 
    callback?: Function): void;

defining that loginWithPassword is a function which will return void
It will accept three parameters:
1st param user will be of type object or a string
2nd param password will always be a string
3rd param callback will be a function
