Sudoku Puzzle

website: https://project-pseudokoders.web.app - Vanilla Javascript ES6, JSON, HTML, Firebase Worked in a team of 4 to develop Sudoku Puzzle which allows user to validate if Sudoku JSON is correct or wrong. Made the checkExactBox function which colors the background of the box which contains the wrong item after validating if the box contains the wrong item. Stored values which is the location of the wrong item to the Set() instead of Map()
