Partial application for login
The task is a little more complex variant of info:task/question-use-bind.
The user object was modified. Now instead of two functions loginOk/loginFail, it has a single function user.login(true/false).
What to pass askPassword in the code below, so that it calls user.login(true) as ok and user.login(fail) as fail?
function askPassword(ok, fail) {
let password = prompt("Password?", '');
if (password == "rockstar") ok();
else fail();
}
let user = {
name: 'John',
login(result) {
alert( this.name + (result ? ' logged in' : ' failed to log in') );
}
};
*!*
askPassword(?, ?); // ?
