JavaScript Constants - Defining Multiple Functions

Question

I've been trying to get multiple functions working in 1 const, but it either does not work (Uncaught SyntaxError: Unexpected identifier) or I'm missing something, and I hope someone can help.

Why does this work:

const dynamicresponse = {
    login(response) {
        alert(response);
    }
}

And why does this not work?

const dynamicresponse = {
    login(response) {
        alert(response);
    }

    adminsearchuser(response) {
        alert(response);
    }
}

And is there a way to get the example above working?

{ login(response) { ... } } is shorthand for { login: function() { ... } } (MDN). As @connexo already mentioned, you're missing commas and therefore get a syntax error. — FK82

You're missing a comma after the body of your login() method.

const dynamicresponse = {
    login(response) {
        alert(response);
    },

    adminsearchuser(response) {
        alert(response);
    }
}

dynamicresponse.login('foo')
dynamicresponse.adminsearchuser('foo')

The notation you tried is used on Javascript class objects.

I knew I was probably missing something, but did not know there needs to be a comma at the end. This fixed my issue, thanks!
