Full Stack Web Development MASTERY Course - Novice to Expert - Asynchronous CRUD Operations Using FS Modules

This video tutorial covers seven challenges related to asynchronous thread operations using Node.js. It begins with creating a folder and progresses through creating, appending, reading, renaming, and deleting files, concluding with removing the directory. The tutorial emphasizes using Node.js file system (FS) module functions like mkdir, writeFile, appendFile, readFile, rename, unlink, and rmdir, with a focus on handling errors and using UTF-8 encoding for reading files.

What is the main focus of the lecture on asynchronous thread operations?

• To learn about synchronous CRUD operations

• To perform asynchronous thread operations challenges

• To understand the basics of JavaScript

• To explore different programming languages

What is the first step in the asynchronous thread operations challenge?

• Rename a file

• Delete a folder

• Create a folder named async crud

• Create a file

Which function is used to write data to a file in the async crud folder?

• readFile

• deleteFile

• appendFile

• writeFile

What function is used to add more data to the end of an existing file?

• writeFile

• appendFile

• readFile

• renameFile

Which encoding is used to read data without getting buffer data?

• UTF-8

• Base64

• ASCII

• Binary

What is the purpose of the rename function in the challenges?

• To change the file's content

• To delete a file

• To change the file's name

• To create a new file

What happens if you try to unlink a non-existent file?

• Nothing happens

• An error is thrown

• The folder is deleted

• The file is created

Which function is used to delete a file in the async crud folder?

• eraseFile

• deleteFile

• unlink

• removeFile

What is the final step in the asynchronous thread operations challenge?

• Create a new file

• Append data to the file

• Rename the folder

• Delete the folder

What is the purpose of using a callback function in these challenges?

• To rename files

• To delete folders

• To create new files

• To handle errors and execute code after an operation
