JSON multiple choice questions List


JSON stands for JavaScript Object Notation. JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. JSON is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C-family of languages (C, C++, JavaScript, and so on). These properties make JSON an ideal data-interchange language.

What are JSON objects?

JSON objects are simply unordered collections of name-value pairs. In other words, a JSON object is used to store data in a structured format.

JSON value type:

JSON values can be one of the following data types:

  • A string
  • A number
  • An object (an unordered collection of key-value pairs)
  • An array (an ordered sequence of values)
  • A boolean (true or false) 

How to create JSON ordered pairs?

To create an ordered pair in JSON, you must use the "pair" keyword. The format for creating an ordered pair is as follows:

  • pair : 
  •   first :
  •   second :

How to quickly create JSON text?

There are many ways to create JSON text. One way is to use a string variable and the other way is to use a JSON object. 

JSON data:

It is a format that is used to store data in a JavaScript Object Notation (JSON) file. These files are often used in web applications to store data that is needed by the application, such as user settings or application configuration. JSON data can be stored in a text file or a database and can be read by any programming language that supports JSON parsing.

What is a JSON string?

These strings are used to store and transmit data. They are typically used to transmit data between a server and a web application. JSON strings are enclosed in double quotation marks and can contain any valid JSON value, including numbers, strings, arrays, objects, and even other JSON strings. JSON strings can be created using the json_encode() function in PHP, or they can be created manually by surrounding a value with double quotation marks.

JSON array:

A JSON array is an ordered collection of values. An array begins with "[" (left bracket) and ends with "]" (right bracket). Values are separated by "," (comma).

How to parse JSON string?

To parse a JSON string, you need to use the JSON.parse() method. This method parses a JSON string and returns an object.

What are java strings?

Java strings are simply a sequence of characters. A string can be created using double quotes:

  • "this is a string"

Javascript object:

In JavaScript, an object is a collection of unordered properties. Properties in objects are usually defined using the syntax "property_name": "property_value". However, you can also use the dot notation to access and set properties.

What is ASCII code?

ASCII code is a code used to represent characters in digital devices. ASCII stands for American Standard Code for Information Interchange. It was originally developed by ANSI (American National Standards Institute) in 1963. ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters.

JSON elements:

JSON elements are essentially pieces of data that are stored in a JSON file. They can be anything from numbers, strings, objects, or even arrays.

What are JSON procedures?

JSON procedures are a set of rules or instructions that are followed in order to complete a task. In computer programming, a procedure is often written as a sequence of commands or steps. These procedures can be executed by computers in order to perform specific tasks or functions.

The file extension of JSON:

File extension of JSON is the .json. This file format was created by Douglas Crockford. JSON is a text-based, human-readable format for representing simple data structures and associative arrays (called objects).

Correct MIME type:

The correct MIME type for JSON is application/json. JSON is a text-based format that is easy for humans to read and write, and easy for machines to parse and generate. JSON can be used in many different ways: as a simple data format that is easy to read and write; as an efficient binary data format; or as a reliable message format. JSON is also a good choice for storing data in databases because it is easy to query and update.

JSON parsing:

Parsing JSON is the process of converting a JSON string into a JavaScript object.

This can be done using the JSON.parse() method in JavaScript, which parses a string and returns a JavaScript object.

What are the main structures compose JSON?

JSON's main structures are objects, arrays, and key-value pairs. Objects are composed of keys and values, where keys are strings and values can be either strings or other objects. Arrays are ordered lists of values, where each value can be either a string or another object.
