# Write a program to determine color of a chessboard square

## Problem description:

You are given coordinates, a string that represents the coordinates of a square on the chessboard. Below is a chessboard for your reference.

Return true if the square is white, and false if the square is black.

The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first, and the number second.

## Example #1:

Input:coordinates = "a1"Output:false Explanation: From the chessboard above, the square with coordinates "a1" is black, so return false.

## Example #2:

Input:coordinates = "h3"Output:true Explanation: From the chessboard above, the square with coordinates "h3" is white, so return true.

## Problem solution:

const squareIsWhite = (coordinates) => { return (coordinates[0].charCodeAt() + parseInt(coordinates[1])) % 2; } console.log(squareIsWhite('a1')) // false
