This question already has an answer here:

Why is using “for…in” with array iteration a bad idea? 25 answers

iterating over an array using

for(item in ['a', 'b']) {
  console.log(item)
}

will give you the array indexes: 0, 1

You are looking for

for(const item of ['a', 'b']) {
  console.log(item)
}

And that will print values: a, b
