Why was props redefined in Counter.js? let index = props.index;

'Index' prop was passed down to the 'Player' component from the 'App' component index={index}, then down to the 'counter' component via index={props.index}.

In Counter.js, index was then redefined as let index = props.index;

to be used in the button: <button className="counter-action decrement" onClick={() => props.changeScore(index, -1)}> - </button>

My question is why did we redefine index? It works with: <button className="counter-action decrement" onClick={() => props.changeScore(props.index, -1)}> - </button>
