Creating a Sudoku Solver Using Backtracking in JavaScript

Short summary

A step-by-step tutorial for building a Sudoku solver in JavaScript using the backtracking algorithm. Covers finding empty cells, validating moves against row/column/box constraints, and recursively solving the board with undo-on-failure logic. Includes complexity analysis (O(9^n)) and notes on real-world backtracking applications.
