This article mainly explains "why the object is formatted by JSON". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn why objects are formatted by JSON.
JSON is formatted as a JavaScript object
The JSON format is syntactically the same as the code for creating JavaScript objects.
Because they are similar, JavaScript programs can easily convert JSON data into JavaScript objects.
JSON grammar rules
The data is a key / value pair.
The data is separated by commas.
Curly braces save objects
Square brackets save array
JSON data-A name corresponds to a value
JSON data is formatted as key / value pairs, just like JavaScript object properties.
The key / value pair includes the field name (in double quotes), followed by a colon, followed by the value:
"name": "Runoob"
JSON object
The JSON object is saved in curly braces.
As in JavaScript, an object can hold multiple key / value pairs:
{"name": "Runoob", "url": "www.runoob.com"}
JSON array
The JSON array is kept in square brackets.
As in JavaScript, arrays can contain objects:
"sites": [
{"name": "Runoob", "url": "www.runoob.com"}
{"name": "Google", "url": "www.google.com"}
{"name": "Taobao", "url": "www.taobao.com"}
]
In the above example, the object "sites" is an array containing three objects.
Each object is the information of the site (site name and site address).
