Create Grid Javascript

grid.js

// uses es6 syntax but can swap out the "lets" and "consts" if you need to use es5
function createGrid(numberOfRowsAndColumns) {
  const grid = [];

  for (let i = 0; i < numberOfRowsAndColumns; i++) {  // upper for-loop creates the rows
    const row = [];

    for (let j = 0; j < numberOfRowsAndColumns; j++) { / lower for loop creates the individual columns
 
      const columnValue = Math.floor(Math.random() * 100); // generates a random value between 1 and 100
      row.push(columnValue);
    }
 
    grid.push(row);
  }

  return grid;
}

const newGrid = createGrid(5);

 Should create a grid (2D array) looking something like:
[ [ 46, 12, 77, 86, 19 ],
