A functional implementation of (a scalable version of) them 2048 game.
By default this implementation follows 2048 exactly - a 4x4 board is created with a 2 or 4 entered in two randomly chosen blocks. Moves can then be performed on a board using move.
It can be scaled to any size with options.
For fun.
Implementation is just 1kb minified and gzipped and consists of 2 pure functions: createBoard and move.
createBoard(boardSize?: number = 4, startWith?: number = 2): Board`Creates a 2048 game board (square) of the optionally given size with the optionally given number of squares
move(board: Board, direction: 'UP' | 'DOWN' | 'LEFT' | 'RIGHT', options?: MoveOptions): MoveResult
// MoveOptions
{
numbers?: number[] = [2,4],
winAt?: 2048
}
// MoveResult
{
board: Board;
score: number;
won: boolean;
}Performs a move on the given board and returns a the next board. Optionally accepts which new numbers could be generated into an empty square.
Return value is an object containing the next board, the points for the move, and whether the move resulted in a win based on the options supplied to the move.
Throws a game over error if no new moves remain.
