Whenever I come back to writing JavaScript after a long break, I always forget how to correctly return objects from lambda expressions, and end up with this:

    () => {
       foo: "bar";
       baz: "qux";
    }

Thankfully TypeScript warns me it's a ()=>void function instead of whatever was expected in the context. I scratch my head for a while and then remember:

    () => ({
        foo: "bar",
        baz: "qux"
    });
