Can JSON have lists?

Can JSON have lists?

Array Datatype in JSON Similar to other programming languages, a JSON Array is a list of items surrounded in square brackets ([]). JSON arrays can be of multiple data types. JSON array can store string , number , boolean , object or other array inside JSON array. In JSON array, values must be separated by comma.

Can a JSON value be an array?

Arrays in JSON are almost the same as arrays in JavaScript. In JSON, array values must be of type string, number, object, array, boolean or null. In JavaScript, array values can be all of the above, plus any other valid JavaScript expression, including functions, dates, and undefined.

How do you write an array of objects in JSON?

JSON Syntax

1. Objects are enclosed in braces ( {} ), their name-value pairs are separated by a comma ( , ), and the name and value in a pair are separated by a colon ( : ).
2. Arrays are enclosed in brackets ( [] ), and their values are separated by a comma ( , ).

How list is represented in JSON?

A resource representation, in the JSON format, is a complex JSON object. Lists of items and nested data structures are represented as JSON arrays and nested JSON objects. A resource that returns a list of items, represents those items in the following standard format: {“data”: [{…},{…}]}

How does JSON store key value pairs?

In order to set a key-value pair in a KiiObject, call the set() method of the KiiObject class. The set() method has an overloaded version for each data type. Specify a key-value pair as arguments of the set() method. The specified key-value pair will be saved at the first level of the JSON document hierarchy.

How does a JSON array look like?

A JSON array contains zero, one, or more ordered elements, separated by a comma. The JSON array is surrounded by square brackets [ ] . A JSON array is zero terminated, the first index of the array is zero (0). Therefore, the last index of the array is length – 1.

What is key-value in JSON?

A JSON object contains zero, one, or more key-value pairs, also called properties. The object is surrounded by curly braces {} . Every key-value pair is separated by a comma. The order of the key-value pair is irrelevant. A key-value pair consists of a key and a value, separated by a colon ( : ).

What types of values can you have in JSON key value pairs?

JSON is basically a collection of name/value pairs, where the name will always be a string and values can be a string (in double quotes), a number, a boolean (true or false), null, an object, or an array. Each name-value pair will be separated by a comma.

Can JSON contain numbers?

JSON is purely a string with a specified data format — it contains only properties, no methods. So for example, a single string or number would be valid JSON. Unlike in JavaScript code in which object properties may be unquoted, in JSON only quoted strings may be used as properties.

What is a JSON list?

JSON is a generic data format with a minimal number of value types: strings, numbers, booleans, lists, objects, and null. Although the notation is a subset of JavaScript, these types are represented in all common programming languages, making JSON a good candidate to transmit data across language gaps.

What is a simple JSON?

JSON is a simple, text-based way to store and transmit structured data. By using a simple syntax, you can easily store anything from a single number through to strings, arrays, and objects using nothing but a string of plain text.

What is JSON and what is JSON used for?

JSON stands for JavaScript Object Notation . JSON is a language-independent text-based representation of structured data. It is very similar to XML. The JSON data is mainly used to represent the key-value pairs and array data types. It is a very light-weight data format that is used for transmits, store data for web programming.

Is JSON similar to XML?

XML stands for “Extensive Markup Language” and is written in a similar way as followed by HTML, whereas JSON stand for “JavaScript Object Notation” which is a subset of the JavaScript syntax and is completely language-independent.
