The library contains a function which detects a winner in tic-tac-toe game.

The function takes two parameters:

  1. The field in the form of two-dimensional array with length equal to the number of rows & columns in the field. The symbol representing a cross or a zero can be any user-defined token or a string. An empty cell in the field should be represented by an empty array element or an empty string.

  2. A number defining the quantity of symbols in succession to be considered as a win.

The function returns an object with the following properties:

  • winnerDetected, boolean, which is false in case of draw game;

  • winnerSymbol, number or string;

  • location, two-dimensional array where each element is an array with a row & column number of the cell containing one of the symbols in winning combination;

  • lastPoint, an array with the number of the row & column of the last symbol in wininng combination;

  • type, string ('row', 'column', 'diagonal-up-right', 'diagonal-up-left' and 'draw game').
