const Button = myFunc();

Now from inside myFunc, I want to get the string "Button" (even before it is assigned to it). Is that possible?

Edit:

I see a lot of comments asking why this is even needed. I'm creating a React component by extending an existing component and adding styles to it (via a new style element at the document head). I want the new class to be called by ".RedButton", for example:

const RedButton = extend(Button)`
  color: red;
`;

...

const extend = OriginalComponent => {
  
  const newComponentName = ... // Here I need the use of "RedButton"
  ...
};
