Why does a constructor function name have to start with uppercase? Is it a name practice or does it have functionality?

In Javascript, why does a constructor function name have to start with uppercase? Is it a naming practice or does it have functionality so that if you don't start with an uppercase something won't work as it supposed to?

Hi Joe,

Whenever you have a function that you're defining as a class it's best practice to use a capital letter as that is the common naming convention between languages and it's much more clear than what a lowercase letter is, that said it plays no part in how the code actually functions so you can call it anything you like.
