How to go another level deeper in an array [duplicate]

Question

I've got an array which has two levels (sorry if that's the wrong terminology) and I can access the first level but I want to go another level down.

Could someone point me in the right direction so I can access that data and output it?

Fiddle here - https://jsfiddle.net/ep2Lqzum/

var myStringArray = [
    ["a", "b", "c"],
  ["d", "e", "f"]
];

var arrayLength = myStringArray.length;
for (var i = 0; i < arrayLength; i++) {
  console.log(myStringArray[i]);
}

try this myStringArray[i][0]) it would in your case select a and d — Carsten Løvbo Andersen

The "level" is called a dimension. You have a 2-dimensional array - it can be n-dimensional. — fdomn-m

Use a second for loop to iterate through the deeper level of the array — Sijan Bhattarai

Use another iteration inside the outer loop.

Here I use .foreach() but you can use any kind of loops you want.

Now you can access the deeper level of the array.

let myStringArray = [["a", "b", "c"],["d", "e", "f"]]
myStringArray.forEach(array => {
  console.log(array)
  array.forEach(character => {
    console.log(character)
  })
})
