How To Map An Array With Unknown Nesting Levels?

I have an array of comments which can have answers, so every element (comment) of the array can have nested elements (comments) and the nesting level is unknown, but I need to rend

Solution 1:

You would use a recursive function. Recursive means that the function calls itself, or in the case of React, a component that returns itself as a child.

Here is an example which renders the value as a paragraph element, and then renders the child comments.

functionComment(props) {
    return (<><p>{props.value}</p>
        {props.comments ? 
            props.comments.map(comment => {
                return <Commentcomments={comment.comments} />
            })
        : null}
    </>)
}

Solution 2:

You can render its recursively

const data = [
  {
    "value": "awesome",
    "comments": [
      {
        "value": "thanks""comments": null
      },
      {
        "value": "really awesome",
        "comments": [
          "value": "thanks again",
          "comments": null
        ]
      }
    ]
  }
]

constCommentItem = (props) => {
  return (
    <div>{props.item.value}</div>
    {
      Array.isArrray(props.item.comments) && 
      props.item.comments.length >= 1 &&
      props.comments.map(comment => (
        <CommentItemitem={comment.comments}/>
      )
    }
  )
}

return data.map(comment =><CommentItemitem={comment}/>)
