JSON - Altogic Docs

Since Altogic exposes RESTful APIs for your application services and JSON is a key data format in RESTFul APIs, it is important to introduce JSON briefly. 
JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is mainly used storing data in document databases and transporting data between different applications, primarily between a server and web applications. JSON is also frequently used in RESTFul APIs to provide data in request and response bodies. Below is an example JSON document summarizing a menu of a restaurant.

JSON supports the following two data structures;
Collection of name/value pairs
An ordered list of values − It includes arrays, lists, or sequences, etc.
A name/value pair consists of a field name (in double quotes), followed by a colon, followed by a value. So in the below example, the name is "firstName," and the value is "John." 
1
"firstName": "John"
Copied!
Please note that that for text values, you need to put them between double quotes; however, for numbers, boolean values, or null values, you do not need double-quotes.
