Best way to iterate over a multidivisional array using forEach JavaScript Google script

What is the best way to iterate a multidivisional array using forEach JavaScript Google script?

I came up with this.

values.forEach(function(row){
  values[0].forEach(function(_,col){
    console.log(row[col])
  });
});

While it works I have a feeling there is a better way to write it

    You can directly call forEach on the inner array:

    let values = [[1,2,3], [4,5,6]];
values.forEach(row => row.forEach(x => {
  console.log(x);
}));

    You can iterate directly over row:

    values.forEach(function (row) {
  row.forEach(function(col) {
    console.log(col);
  });
});

    Alternatively, you can use arrow functions and make it into a one-liner:

    values.forEach(row => row.forEach(col => console.log(col)));

    You could also use a for..of loop:

    for (const row of values) {
  for (const col of row) {
    console.log(col);
  }
}
