Does this alternative solution work?

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

  • Generates 2D array of spaces.
  • @return {Array} An array of space objects */

    createSpaces() { const spaces = [];

    for (let i = 0; i <= this.rows; i++) {
        let spaces = new Space(i, undefined);
        spaces.push(space);
    
    for (let i = 0; i <= this.columns; i++) {
        let spaces = new Space(undefined,i);
        spaces.push(space);
    }
    return spaces;
    

    } }

Did you try this? I would not expect it to work for a few reasons:

  • spaces are intended to be created by passing in both coordinates but this code only provides one of them
  • the columns should be arrays of spaces, not just individual spaces
  • the loops would need to be nested to create the column arrays (as shown in the example)
