JSON (JavaScript Object notation) is a lightweight data interchange format. Easy for people to read and write. It is also easy to machine parse and generate. It is based on JavaScript programming Language, Standard ECMA-262 a subset of 3rd Edition-december 1999. JSON uses a completely language-independent text format that makes JSON an ideal data exchange languag
First,JSON (JavaScript Object Notation) is a simple data format that is lighter than XML. JSON is constructed in two structures:1, the collection of "name/value" pairs (A collection of name/value pairs). In different languages, it is understood as objects (object), record (record), structure (struct), Dictionary (dictionary), hash table (hash table), keyed list (keyed list), or associative array (associativ

contents of the curly brace wrapped {}, the data structure is {key1:value1, key2:value2, ...} key-value pair structure. In an object-oriented language, key is the property of the object, and value is the corresponding values. Key names can be represented using integers and strings. The type of the value can be any type. Array: The array in JS is square brackets [] wrapped content, data structure for ["Java", "JavaScript", "VB", ...] index structure.

FK, this format is completely incorrect! It is invalid. Imagine,The JSON format is white. It is a subset of Javascript. A valid json object is an object in javascript.But:
{Size: 4, specialName: "just a test", [1, 2, 4]}
Is it a legal javascript Object ????
Obviously, it is not. Because [1, 2, 3, 4] is inaccessible, it does not correspond to an attrib
Because of the many advantages of JSON data format, data transfer is now the most popular format for data transmission. So more and more projects use this format to transmit data before and after the platform.
