I'm new to building apps and coding, and as a side project I'm trying to make a chessboard using React and JavaScript. I'm currently trying to figure out a way to create a unique id key in the 2D for loop of the Chessboard component below:

This is the code for the Tile component

import './Tile.css';

const WhiteTile = () =>
{
   return(
      <div className='TileWhite'></div>
   )
}

const AquaTile = () =>
{
   return(
      <div className='TileAqua'></div>
   )
}


const ENUM_OBJECT = 
{
   whiteTile: <WhiteTile/>,
   aquaTile: <AquaTile/>,
};

function Tile({tileType}) 
{
   return ENUM_OBJECT[tileType]
}

export default Tile;

This is the code for the chessboard component

import React from 'react';  
import '../ChessBoard/Chessboard.css'
import Tile from './Tile';



function ChessBoard()
{  
    const xCoordinates = ["a", "b", "c", "d", "e", "f", "g", "h", "0"];


    const yCoordinates = ["0", "1", "2", "3", "4", "5", "6", "7", "8"];
    
    const coordinatesBoard = []; 

    const RenderCoordinates = () =>
    {

        for(let y = yCoordinates.length; y > 0; y--)
        {
            for(let x = 0; x < xCoordinates.length - 1; x++)
            {   
                if(x % 2 === 0)
                {
                    coordinatesBoard.push(<Tile tileType={"whiteTile"} key={''}></Tile>);
                }
                else
                {
                    coordinatesBoard.push(<Tile tileType={"aquaTile"} key={''}></Tile>);

                }
            }
        }
        return coordinatesBoard; 
    }


    return(<div className="App">
            {<RenderCoordinates/>}
            </div>)
    
}

export default ChessBoard;

I have tried using the map function before

const RenderTiles = () =>
    {
        const cBoard = coordinatesBoard.map((xyCoordinates, index) =>
        {
                if(index % 2)
                {
                    return(
                    <div className ="Tile1" key={index}>
                        {xyCoordinates}
                    </div>
                    )
                }
                else 
                {
                    return(
                    <div className ="Tile2" key={index}>
                        {xyCoordinates}
                    </div>
                    )
                }
        });

        return cBoard
    }

Also studied useState

const [counter, setCounter] = useState(0);

    const increment = () => 
    {
    
        setCounter(counter + 1);
    }

Tried to insert counter here but encountered infinite loop (from chessboard function)

coordinatesBoard.push(<Tile tileType={"whiteTile"} key={counter + 1}></Tile>);

I expect the counter to increment every time a tile is pushed onto the board please help.
