Loop through array with arrays using Javascript

I have a var which contains an array with multiple arrays. I am trying to get the values of each cell to print them into an HTML table.

I want to use a foreach but since I have no idea how to do it, even though I've seen examples on the internet, I tried to do this using a for loop but cannot make it work.

Is there an easier way to do this?

This is the code I have:

var DetalleFactura = response[0]['DetalleFactura']; //var with the array I'd like to print

for (let i = 0; i < DetalleFactura.length; i++) {
    var value = parent[i];
    for (let j = 0; j < parent[i].length; j++) {
        /*print values here*/
    }
}

Per your question here's how you can print the values like you indicated using forEach.

DetalleFactura.forEach((subArr)=>{
subArr.forEach(val => {
console.log(val);
   })
});

You can also just use array.flat() to get the results you want.

const flatArr = DetalleFactura.flat();
