On 1:27 of this video he says,
"So, I'll create a routes object by typing const routes."
then created an like so,
const routes = ();
would it not be like this,
const routes = {};
is this an ES6 way of defining objets or JSX? I'm not 100% sure.

return <Router ...>
...
</Router >;
Which seems more legible to me. He switches between the two styles it seems.

19,315 PointsI'm aware that it's not going to be empty, I just defined it with nothing inside so you can see what i'm talking about.
Ok so that means that {} is not how you define an object when using JSX but instead it's parenthesis.
