What is the proper format of a JSON Array file?

Well let’s start off by understanding what JSON is, JavaScript Object Notation. It’s a derivative of JavaScript that allows data to be passed between a server & a website in the form of objects. It’s similar to XML, except the JSON syntax is less invasive than XML and so it ends up having a bit of a smaller file size.

Below you’ll find a basic sample of a JSON array that has two objects.

[
  {
    "title":"Name of Article 1",
    "image":"/images/press_article1.png",
    "timestamp":"March 2011"
  },
  {
    "title":"Name of Article 4",
    "image":"/images/press_article2.png",
    "timestamp":"March 2011"
  }
]

Note: There are no commas on the last line of each array.

There are many other structures of JSON files, I highly suggest checking out the wiki page for other uses.
