how to make a tile generation system in javascript

// get the table body element
const table = document.getElementById("tbody");

// generate the tiles
for(var y = 0; y < 10; y++) {
	// creating rows elements for the table
	tableRow = document.createElement("tr");
  	// putting the new rows into the table
  	table.appendChild(tableRow);
  	for(var x = 0; x < 10; x++) {
    	// creating the tiles
    	tile = document.createElement("td");
      	// displaying the tiles
      	tableRow.appendChild(tile);
    }
}
