Variable naming inconsistency in the tutorial documentation

Hi,
I have just used the React tutorial, it is great!
It helps a lot to learn the basic.

While working, I have spotted a small inconsistency on https://github.com/reactjs/reactjs.org/blob/main/content/tutorial/tutorial.md

When creating the buttons to move into the history, we are using a move variable that we are sending to jumpTo:

But jumpTo use step to make the moves:

I suggest that we switch the move and step variables of the render function to make the tutorial more understandable by beginners:

I can push a merge request for the documentation but I do not know how to change the source code linked by @gaearon on codepen:
https://codepen.io/gaearon/pen/gWWZgR?editors=0010

Is there a way to do that?

Start with content/tutorial/tutorial.md and read the tutorial's render function alongside jumpTo to confirm the variable naming inconsistency. Check the linked CodePen to determine whether it is also part of the requested documentation change. Done means the tutorial uses consistent names and the relevant example remains understandable to beginners.
