How do I use forEach to loop through this

Question

let arr = [{
question:{
 q1 : 123,
 q2 : 44
}
}];

I've tried using forEach loop to do it, but it returns nothing.

There's only one element in `arr` so why `.forEach()`? `.forEach()` doesn't "return" anything -> [How do I ask a good question? - Help Center - Stack Overflow](https://stackoverflow.com/help/how-to-ask) — Andreas, Jun 28 '20 at 15:38

If it's an array then you can do either map or forEach.

  arr.forEach()

However you have to pay attention to the internal structure of the item as well, ex. in your case

  arr.forEach(item => {
    console.log(item.question.q1)
  })

And if you want the transformation, then

  const transformedArr = arr.map(item => item.question.q1)
