Here is a simple implementation of sudoku solver in JavaScript using backtracking algorithm:
index.tsx1223 chars59 lines
You can call this function with a 2D array of 9x9 grid with empty cells denoted by '.' character. The function uses backtracking algorithm to solve the sudoku puzzle. It checks each empty cell and tries to fill it with a number from 1 to 9 which satisfies the sudoku rules. If it finds a valid number, it moves to the next empty cell and repeats the process. If it reaches the end without any violations, then it has found a valid solution.
