Full Stack Web Development MASTERY Course - Novice to Expert - JSON in Node.js

The video tutorial covers the basics of JSON, its role in Node.js, and how to create JavaScript objects. It explains converting JavaScript objects to JSON using the stringify function and parsing JSON back to JavaScript objects with the parse function. The tutorial also demonstrates file operations in Node.js, such as writing and reading JSON files, and emphasizes the importance of JSON in APIs.

What is JSON primarily used for in web development?

• Creating animations

• Storing and transporting data

• Styling web pages

• Managing user sessions

Which of the following is a key difference between JavaScript objects and JSON?

• JSON requires both keys and values to be in double quotes

• JavaScript objects require keys to be in double quotes

• JSON uses single quotes for keys

• JavaScript objects cannot store numbers

What does the stringify function do?

• Converts a JSON string into a JavaScript object

• Removes properties from a JavaScript object

• Converts a JavaScript object into a JSON string

• Adds new properties to a JSON object

Why can't you directly access specific values from a JSON string?

• JSON strings are too large to handle

• JSON strings are read-only

• JSON strings need to be parsed into JavaScript objects first

• JSON strings are encrypted

What is the purpose of the parse function in JSON handling?

• To encrypt JSON data

• To validate JSON data

• To convert a JSON string into a JavaScript object

• To convert a JavaScript object into a JSON string

Which Node.js module is used for file operations like reading and writing JSON data?

• HTTP module

• Path module

• FS module

• OS module

What is the advantage of using asynchronous functions in Node.js file operations?

• They are faster than synchronous functions

• They are easier to write

• They prevent the process from blocking

• They use less memory

How can you ensure that a JSON file is read as a string in Node.js?

• By using the ASCII encoding

• By using the UTF-8 encoding

• By using the Base64 encoding

• By using the binary encoding

What is the file extension for JSON files?

• .json

• .js

• .xml

• .txt

What is a common use case for JSON in web applications?

• To style web pages

• To manage user authentication

• To create animations

• To store and transport configuration data
