How to set up "forEach" syntax using arrays.

Question

In the JSON formatting of SharePoint lists, the "forEach" using arrays does not work properly, and the output result becomes blank.

The following is a code sample that does not work properly.

It is really frustrating even though it is a simple thing.

(Output Example)

When the value of the $Content column is "AA//BB//CC", the desired output result is "aaa".

{   
  "$schema": "~~~",
  "elmType": "div", 
  "forEach": "Iterator in split([$Content],'//')",
  "txtContent": "a"
}

Answer 1

I solved it myself. I don't know why I need to write this though.

{
  "$schema": "~~~",
  "elmType": "div",
  "children": [
    {
      "forEach": "Iterator in split([$Content],'//')",
      "elmType": "div",
      "txtContent": "a"
    }
  ]
}
