I dont know what I did wrong, but here it is my new test and the output.

class Space {
  constructor(x, y) {
    this.x = x;
    this.y = y;
    this.id = `space-${x}-${y}`;
    this.token = null;
  }
}

class Board {
  constructor() {
    this.rows = 6;
    this.columns = 7;
    this.spaces = this.createSpaces();
  }

  createSpaces() {
    const spaces = [];

    for (let x = 0; x < this.columns; x++) {
      const column = [];

      for (let y = 0; y < this.rows; y++) {
        const space = new Space(x, y);
        column.push(space);
      }

      spaces.push(column);
    }
    return spaces;
  }
}

const myBoard = new Board();

console.log(myBoard.spaces);
