What kind of data structure is JSON?
JSON is a data interchange format that is easy to parse and generate. JSON is an extension of the syntax used to describe object data in JavaScript. Yet, it's not restricted to use with JavaScript. It has a text format that uses object and array structures for the portable representation of data.Apr 20, 2021.
What type of data format is used in JSON?
JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).Jul 3, 2023.
Structs for JSON Data
Braces {} denote a JSON object, and contain a comma-delimited list of zero or more members, consisting of a name and value separated by a colon.
A member can have a value that is an object or an array.
Brackets ( [] denote a JSON array, which contains zero or more values separated by commas
JSON defines only two data structures: objects and arrays. An object is a set of name-value pairs, and an array is a list of values. JSON defines seven value types: string, number, object, array, true, false, and null. The following example shows JSON data for a sample object that contains name-value pairs.

Introduction
Le JavaScript Object Notation (JSON) est un format standard utilisé pour représenter des données structurées de façon semblable aux objets
Utilisation
Le JSON se présente sous la forme d'une chaîne de caractères utile lorsque vous souhaitez transmettre les données sur un réseau
Propriétés
Un peu plus haut, nous avons dit qu'un objet JSON n'était ni plus ni moins qu'un objet Javascript tout à fait normal et c'est généralement le cas
Inconvénients
Mais on a pas toujours cette chance il est possible de recevoir la réponse JSON sous la forme d'une chaîne de caractères et il faut alors la convertir en objet
Commentaire
Comme vous pouvez le deviner, stringify() fait exactement le contraire
Fonctionnement
On commence par créer un objet JavaScript puis on vérifie son contenu avant de le convertir en chaîne de caractères JSON avec stringify() en sauvegardant au
Is JSON a string or a JavaScript Object?
JSON exists as a string — useful when you want to transmit data across a network
It needs to be converted to a native JavaScript object when you want to access the data
This is not a big issue — JavaScript provides a global JSON object that has methods available for converting between the two
What are the different types of JSON data types?
There are only a couple others to introduce
Here is the complete list of JSON data types: string – Literal text that’s enclosed in quotes
number – Positive or negative integers or floating point numbers array – A collection of one or more JSON objects boolean – A value of either true or false with no quotes
What is JSON data structure?
This lesson covers the JSON data structure
JSON is a powerful text based format that supports hierarchical data structures
It is the core structure used to create geoJSON which is a spatial version of json that can be used to create maps
The structure of a JSON object is as follows: The data are in name/value pairs Data objects are separated by commas The ability to store nested or hierarchical data within a text file structure makes JSON a powerful format to use as you are working with larger datasets.
Data structure from json
Open standard file format and data interchange
JSON 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. It is a common data format with diverse uses in electronic data interchange, including that of web applications with servers.
File format for encoding linked data
JSON-LD is a method of encoding linked data using JSON. One goal for JSON-LD was to require as little effort as possible from developers to transform their existing JSON to JSON-LD. JSON-LD allows data to be serialized in a way that is similar to traditional JSON. It was initially developed by the JSON for Linking Data Community Group before being transferred to the RDF Working Group for review, improvement, and standardization, and is currently maintained by the JSON-LD Working Group. JSON-LD is a World Wide Web Consortium Recommendation.
Computer network protocol
JSON-RPC is a remote procedure call protocol encoded in JSON. It is similar to the XML-RPC protocol, defining only a few data types and commands. JSON-RPC allows for notifications and for multiple calls to be sent to the server which may be answered asynchronously.
IETF standard for encrypted data
JSON Web Encryption (JWE) is an IETF standard providing a standardised syntax for the exchange of encrypted data, based on JSON and Base64. It is defined by RFC external text>7516. Along with JSON Web Signature (JWS), it is one of the two possible formats of a JWT. JWE forms part of the JavaScript Object Signing and Encryption (JOSE) suite of protocols.
