How to use comments in JSON

Although traditional comments are not allowed in JSON, there is one work-around.

JSON is data-only, meaning something like this won’t work:

{
  # note: this is out of stock
  "title": "Red Addidas Shoes",
  "price": 50
}

Instead, we can add a new data element to the JSON and just ignore it when we read the JSON into our code.

{
  "_note": "this is out of stock"
  "title": "Red Adidas Shoes",
  "price": 50
}
