JSON, it is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types.
{
"firstName": "Orest",
"lastName": "Smith",
"isAlive": true
}
# In the example above, firstname is an attribute, and the value is "Orest".
JSON (JavaScript Object Notation) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.
JSON is a language-independent data format. It was derived from JavaScript, but many modern programming languages include code to generate and parse JSON-format data. JSON filenames use the extension .json.[2]
Example 1 - String Value Application
JS: { name : 'Orest' }
JSON: { "name" : "Orest" }
Example 2 - Data Types
a. Number
b. String
c. Boolean
d. Array
e. Object
f. Null
Example 3 - Short Biography of a Person in short facts
{
"firstName": "Orest",
"lastName": "Smith",
"isAlive": true,
"age": 27,
"address": {
"streetAddress": "21 2nd Street",
"city": "New York",
"state": "NY",
"postalCode": "10021-3100"
},
"phoneNumbers": [
{
"type": "home",
"number": "123 654-7809"
},
{
"type": "office",
"number": "098 765-4321"
},
{
"type": "mobile",
"number": "123 456-7890"
}
],
"children": [],
"spouse": null
}
Example 4 - Parsing JSON in JS
var p = JSON.parse(json_string);
