The literal representation of a json--object

JSON is a special representation of the literal of JS, which uses text to represent JS object information, which is essentially a string

var // This is an object, note that the key name can also be wrapped in quotation marks var // This is a JSON string, which is essentially a string

To convert from a JS object to a JSON string, use the Json.stringify () method:

var // The result is ' {' A ': ' Hello ', ' B ': ' World '} '

To implement a conversion from JSON to a JS object, use the Json.parse () method:

var // The result is {a: ' Hello ', B: ' World '}

Storing JSON in array form:

<script>    var person = [        "FirstName": "Brett", "LastName": "McLaughlin" },        "FirstName": "Jason", "LastName": "Hunter" }    ];    Console.log (person[0].firstname); // Brett</script>
