The Depths of JavaScript: Minesweeper in 247 Bytes

A developer and collaborator DNEK code-golfed a fully functional Minesweeper game into just 247 bytes of JavaScript, featuring an 8x8 board, left-click to open, right-click to flag, recursive cell opening, and win detection. The journey started from a 658-byte version and was refined over months of collaborative optimization.

Background

Code golf is a programming practice where developers strive to solve problems in the fewest possible characters. JavaScript's flexibility makes it a popular target for such challenges.
