Why does 

 const Todos = function () {
   ...
 }   
 const todos = new Todos();

work just fine, but 

 const Todos = () => {
   ...
 }   
 const todos = new Todos();

Give a TypeError: Todos is not a constructor error?

Because it is a Arrow function. Try this const todos = Todos();

The arrow function isn't a constructor so calling it with new isn't correct. It's just a regular function so instead try:

const todos = Todos();
