I want to make my grid does not come from html but to reflect the grid created in js that looks in html, vamso, to have empty html. since I want to learn more to use arrays than to focus on html. I do not see how I can make any suggestions? Thank you

var myGrid = [
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  ['x', 1, 2, 3, 4, 5, 6,'o', 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  [0, 1, 2,'o', 4, 5, 6, 7, 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7,'o', 9, 10],
  [0, 1, 'o', 3, 4,'o', 6, 7, 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 'o']
];



for (var i = 0; i < myGrid.length; i++) {
  let row = myGrid[i];

  for (var j = 0; j < row.length; j++) {
    let column = row[j];
    if (column === 'o') {
      console.log('obstacle are in: ' + i + ',' + j);
    }
  }
}

    }

What you need is to write the html directly from your Javascript.

First, you need a function that takes the array as an argument and returns the generated html. For example (using your same code structure - more or less, I have changed the contents of the boxes, but you can easily modify it):

function array2html(grid) {
    var html = "";
    grid.forEach( function(row, i) {
        html += '<div class='row row${i}'>';
        row.forEach( function (cell, j) {
            let char = ".";
            if( cell === "o" ) char = "o";
            if( cell === "x" ) char = "x";
            html += '<div class='col-xs-1 celda' data-num='[${j},${i}]'>${char}</div>';
        }
        html += "</div">;
    }
    return html;
}

Next, you need to modify the DOM to insert that html instead of the previous one.

For example:

$('.container').html(array2html(myGrid));
