Array indexes are zero-based: The first element in the array is 0, the second is 1, and so on.
JSON arrays are written inside square brackets.
Just like in JavaScript, an array can contain objects:
Example(1)
Create JSON array Values
var myObj, i, x = "";
myObj = {
"name":"John",
"age":30,
"cars": ["Ford","BMW","Fiat"]
}
Delete Array Items
Use the delete keyword to delete items from an array:
delete myObj.cars[1];
