Properties and methods

Once you have created your instance, you can access these Read-Only properties:

ws.grid

Returns the puzzle's grid

[
  ["S", "Š", "M", "Y", "W", "X"],
  ["E", "C", "K", "M", "O", "G"],
  ["A", "R", "Z", "O", "R", "A"],
  ["R", "Ê", "N", "F", "D", "I"],
  ["C", "P", "I", "Y", "Q", "A"],
  ["H", "E", "L", "L", "O", "I"]
]

ws.words

Returns the words that were successfully inserted in the grid:

[
  {
    word: "word",
    clean: "WORD",
    path: [
      { x: 4, y: 0 }, // W
      { x: 4, y: 1 }, // O
      { x: 4, y: 2 }, // R
      { x: 4, y: 3 } // D
    ]
  },
  {
    word: "crêpe",
    clean: "CRÊPE",
    path: [
      { x: 1, y: 1 }, // C
      { x: 1, y: 2 }, // R
      { x: 1, y: 3 }, // Ê
      { x: 1, y: 4 }, // P
      { x: 1, y: 5 } // E
    ]
  }
  /* ... */
];

ws.forbiddenWordsIncluded

Returns an Array of forbidden words which were inserted into the grid because no other solution was found after maxRetries:

["CRAP"]

You can also use these methods:

ws.dump()

Returns an Object representing the state of the puzzle. This can be useful if you want to save a game and reuse it later using ws.load(backup).

ws.load(backup)

Loads a game from an Object of a previous dump.

const ws1 = new WordSearch(/* ... */);
const backup = ws1.dump();
const ws2 = new WordSearch().load(backup);
// ws2 is now a copy of ws1

ws.toString()

Returns a String representing the grid of the puzzle. This can be useful if you want to print it to the console.

S Š M Y W X
E C K M O G
A R Z O R A
R Ê N F D I
C P I Y Q A
H E L L O I

ws.read(start, end)

Reads the letters from start to end positions and returns the String it forms. This can be useful to check what letters a user highlighted.

ws.read({ x: 1, y: 0 }, { x: 5, y: 4 }); // "ŠKODA"
