- 1.
JSON stands for ?
- A.
JavaScript Object Notation
- B.
Java Object Notation
- C.
JSON Object Notation
- D.
None Of The Above
Correct Answer
A. JavaScript Object NotationExplanation
JSON stands for JavaScript Object Notation. It is a lightweight data interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It is often used to transmit data between a server and a web application, as an alternative to XML. JSON is based on a subset of the JavaScript Programming Language, and it is language-independent, meaning it can be used with any programming language. JSON is widely used in web development and is supported by most modern programming languages and frameworks.Rate this question:

- 2.
JSON values cannot be one of the following data types.?
- A.
Function
- B.
Undefined
- C.
Date
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
JSON values cannot be one of the following data types: Function, Undefined, or Date. JSON is a lightweight data interchange format that is based on a subset of JavaScript syntax. It is used to represent data in a structured format, and it supports a limited set of data types such as strings, numbers, booleans, arrays, and objects. However, it does not support functions, undefined values, or dates as standalone values. Therefore, the correct answer is "All of the above" because all three options (Function, Undefined, and Date) are not valid JSON values.Rate this question:

- 3.
The file type for JSON files is ?
- A.
.json
- B.
.js
Correct Answer
A. .jsonExplanation
The file type for JSON files is ".json" because JSON (JavaScript Object Notation) is a lightweight data interchange format that is commonly used to store and transmit data between a server and a web application. The ".json" file extension is used to indicate that a file contains data in JSON format, allowing programs and systems to recognize and process the data accordingly.Rate this question:
-
- 4.
The order of json object is always preserved?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The order of a JSON object is always preserved because JSON is a data interchange format that follows a specific syntax. According to the JSON specification, the order of the elements in an object is significant and should be preserved. This means that when a JSON object is serialized or deserialized, the order of the key-value pairs will remain the same. Therefore, the statement "The order of JSON object is always preserved" is true.Rate this question:

- 5.
Why must one use JSON over XML ?
- A.
XML data is typeless while JSON objects are typed
- B.
Data is readily available as JSON object is in your JavaScript
- C.
It is faster and lighter than XML as on the wire data format
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
JSON is preferred over XML for several reasons. Firstly, JSON objects are typed, meaning they provide information about the type of data being stored, while XML data is typeless. This allows for easier and more accurate data manipulation and processing. Additionally, JSON data is readily available in JavaScript, making it easier to work with in web development. Lastly, JSON is faster and lighter than XML as a data format, making it more efficient for transmitting data over the internet. Therefore, all of the given reasons make JSON a better choice over XML.Rate this question:

C. ObjectExplanation
The correct answer is "Object." JSON (JavaScript Object Notation) is a lightweight data-interchange format that is used to transmit data between a server and a web application. JSON supports various data types such as strings, numbers, booleans, arrays, and objects. However, "Object" is not a JSON type because it refers to a specific data structure rather than a data type itself.Rate this question:

From the following which of the following number formats are not used in JSON??
- A.
Octal, Hexadecimal
- B.
Octal , Binary
- C.
Octal , Gate
- D.
Binary , Hexadecimal
Correct Answer
A. Octal, HexadecimalExplanation
JSON (JavaScript Object Notation) is a lightweight data interchange format that is used to transmit data between a server and a web application. JSON does not support octal or hexadecimal number formats. In JSON, numbers are represented in decimal format only. Therefore, Octal and Hexadecimal number formats are not used in JSON.Rate this question:

From the following what does JSONP stand for ?
- A.
Json parsing
- B.
Json padding
- C.
Json procedures
- D.
Json programming
Correct Answer
B. Json paddingExplanation
JSONP stands for JSON padding. JSON padding is a technique used to overcome the same-origin policy restriction in web browsers. It allows a web page to request and load data from a different domain by dynamically adding a tag to the HTML document. The response from the server is wrapped in a callback function, which enables the client-side JavaScript to access and use the data. This technique is commonly used in cross-domain AJAX requests.Rate this question:

- 13.
In JSON does the white space matters ?
- A.
Only within strings.
- B.
Only outside of strings.
- C.
Both inside and outside of strings
- D.
None of the above
Correct Answer
A. Only within strings.Explanation
In JSON, white space only matters within strings. This means that any white space characters (such as spaces, tabs, or line breaks) within a string value will be considered part of the string itself. However, white space outside of strings, such as between key-value pairs or before or after the JSON object, does not affect the interpretation of the data.Rate this question:
-
- 14.
Does JSON support Unicode characters??
- A.
Yes
- B.
No
Correct Answer
A. YesExplanation
JSON does support Unicode characters. Unicode is a standard that represents characters from almost all writing systems in the world. JSON allows the encoding and decoding of Unicode characters, making it possible to include and transmit data in various languages and scripts. This enables the representation of a wide range of characters and symbols in JSON data.Rate this question:

- A.
JSON.toString()
- B.
JSON.serialize()
- C.
JSON.stringify()
- D.
JSON.text()
Correct Answer
C. JSON.stringify()Explanation
The correct answer is JSON.stringify(). This function is used to convert a JavaScript object into a JSON string. It takes the object as a parameter and returns a string representation of the object in JSON format. This is useful when data needs to be sent to a server or stored in a file, as JSON is a widely supported format for data interchange.Rate this question:

Json elements are separated by using which of the following ?
- A.
Comma
- B.
White space
- C.
Line break
- D.
Semi-colon
Correct Answer
